The Long Dark Coal
So, when I was younger my Dad made a little stove from a Folgers coffee tin that burned charcoal. It was really nice for ice fishing! The charcoal would stay hot for a long time and was great for making lunch and warming up frozen hands.
Now, coal isn't charcoal (obviously) but why can't I burn it in a fire?I had just made the trip to desolation point and wanted to boil some water. In my inventory was lighter fluid, matches, tinder bundles and coal. The game said I had no fuel for a fire. Odd (you can get anything to burn with enough lighter fluid and tinder) but whatever. So, I found some scrap wood. Nope, still couldn't burn coal.Now, people burned coal to keep warm and for cooking for hundreds of years. So why can't I?
Can I only ever use coal in a forge? If so, that seems rather silly. It's not about the heat when starting coal. It's about time. It takes time in a fire for coal to transform into it's burnable form. This involves vaporizing some of its components and drying out others.

A fire has to have a 1 hour burn (or longer) time to produce 1 piece of charcoal after it is bruned out. The maximum number of pieces you can get after a long fire is 10, so a 12 hour fire will still only produce 10 pieces of charcoal. 1 hour = 1 charcoal, 2 hours = 2 charcaol, etc. Feb 11, 2018 - Specifically I'm wondering about the coal in the cave at the Camping Area in Milton.

I'm no expert, but you can't just throw coal in a fire and have it start burning. You must plan ahead.
Lighting charcoal would be a close simulation.So in that, the game is not right. The coal should be in the wood fire for 20 minutes before it ignites. But that would require deep modifications to the fire interface. Only letting you add coal to a fire that has existed for 20 minutes is cheaper. It's not about the heat when starting coal. It's about time.

But that would require deep modifications to the fire interface. Only letting you add coal to a fire that has existed for 20 minutes is cheaper.It could also be trivially simple to change a few lines of code for the fire interface to change the rules of use for coal. I think the point is that you need a good bed of coals going before you add coal; that is when your fire is well established and putting out it's optimum heat.
Put coal on a baby fire and it saps the energy of the fire. While waiting for 20 minutes, it's a good time to boil some water or fry a fish.;-)Coal doesn't need to off gas volatile vapors as much as wood does. It will burn when it reaches a certain temperature and if there is oxygen.I'm curious what happens if you try to cook food on the forge once you've got it roaring?
A coal mine in, Belgium.Coal mining is the process of from the ground. Coal is valued for its, and, since the 1880s, has been widely used to generate electricity. And industries use coal as a fuel for extraction of iron from and for cement production. In the and, a coal mine and its structures are a colliery, a coal mine a pit, and the above-ground structures the.
In, 'colliery' generally refers to an underground coal mine. In the, 'colliery' has been used to describe a coal mine operation but nowadays the word is not commonly used.Coal mining has had many developments over the recent years, from the early days of men tunnelling, digging and manually extracting the coal on carts, to large and mines. Mining at this scale requires the use of, trucks, and shearers. Ships have been used to haul coal since Roman times.Small-scale mining of surface deposits dates back thousands of years. For example, in, the Romans were exploiting most of the major coalfields by the late 2nd century AD.The, which began in Britain in the 18th century and later spread to continental Europe and North America, was based on the availability of coal to power. International trade expanded rapidly when coal-fed steam engines were built for the railways and steamships.Until the late nineteenth century coal was mined underground using a pick and shovel, and children were often employed underground in dangerous conditions.
Coal-cutting machines were introduced in the 1880s. By 1912, was conducted with designed for coal mining.Methods of extraction The most economical method of coal extraction from coal seams depends on the depth and quality of the seams, and the and environmental factors. Coal mining processes are differentiated by whether they operate on the surface or underground. Many coals extracted from both surface and underground mines require washing in a. Trucks loaded with coal at the coal mine inWhen coal seams are near the surface, it may be economical to extract the coal using (also referred to as open cast, open pit, mountaintop removal or strip) mining methods. Open cast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the may be exploited.
This equipment can include the following: Draglines which operate by removing the overburden, power shovels, large trucks in which transport overburden and coal, bucket wheel excavators, and conveyors. In this mining method, explosives are first used in order to break through the surface or overburden, of the mining area. The overburden is then removed by draglines or by shovel and truck. Once the coal seam is exposed, it is drilled, fractured and thoroughly mined in strips. The coal is then loaded onto large trucks or conveyors for transport to either the coal preparation plant or directly to where it will be used.Most open cast mines in the United States extract. In Canada (BC), Australia and South Africa, is used for both and metallurgical coals. In open casting for steam coal and is practiced.
Surface mining accounts for around 80 percent of production in Australia, while in the US it is used for about 67 percent of production. Globally, about 40 percent of coal production involves surface mining. Strip mining Strip mining exposes coal by removing earth above each coal seam. This earth is referred to as overburden and is removed in long strips.
The overburden from the first strip is deposited in an area outside the planned mining area and referred to as out-of-pit dumping. Overburden from subsequent strips are deposited in the void left from mining the coal and overburden from the previous strip. This is referred to as in-pit dumping.It is often necessary to fragment the overburden by use of explosives. This is accomplished by drilling holes into the overburden, filling the holes with explosives, and detonating the explosive.
The overburden is then removed, using large earth-moving equipment, such as, and trucks, and trucks, or and conveyors. This overburden is put into the previously mined (and now empty) strip. When all the overburden is removed, theunderlying coal seam will be exposed (a 'block' of coal).
This block of coal may be drilled and blasted (if hard) or otherwise loaded onto trucks or conveyors for transport to the coal preparation (or wash) plant. Once this strip is empty of coal, the process is repeated with a new strip being created next to it.
This method is most suitable for areas with flat terrain.Equipment to be used depends on geological conditions. For example, to remove overburden that is loose or unconsolidated, a bucket wheel excavator might be the most productive. The life of some area mines may be more than 50 years. Contour mining The contour mining method consists of removing overburden from the seam in a pattern following the contours along a ridge or around the hillside. This method is most commonly used in areas with rolling to steep terrain.
It was once common to deposit the spoil on the downslope side of the bench thus created, but this method of spoil disposal consumed much additional land and created severe landslide and erosion problems. To alleviate these problems, a variety of methods were devised to use freshly cut overburden to refill mined-out areas. These haul-back or lateral movement methods generally consist of an initial cut with the spoil deposited downslope or at some other site and spoil from the second cut refilling the first. A ridge of undisturbed natural material 15 to 20 ft (5 to 6 m) wide is often intentionally left at the outer edge of the mined area.
The Long Dark Coal Locations
This barrier adds stability to the reclaimed slope by preventing spoil from slumping or sliding downhill.The limitations of contour strip mining are both economic and technical. When the operation reaches a predetermined stripping ratio (tons of overburden/tons of coal), it is not profitable to continue. Depending on the equipment available, it may not be technically feasible to exceed a certain height of highwall. At this point, it is possible to produce more coal with the augering method in which spiral drills bore tunnels into a highwall laterally from the bench to extract coal without removing the overburden.Mountaintop removal mining. Main article:Mountaintop coal mining is a surface mining practice involving removal of mountaintops to expose coal seams, and disposing of associated mining overburden in adjacent 'valley fills.' Valley fills occur in steep terrain where there are limited disposal alternatives.combines area and contour strip mining methods.
In areas with rolling or steep terrain with a coal seam occurring near the top of a ridge or hill, the entire top is removed in a series of parallel cuts. Overburden isdeposited in nearby valleys and hollows.
This method usually leaves ridge and hill tops as flattened plateaus. The process is highly controversial for the drastic changes in topography, the practice ofcreating head-of-hollow-fills, or filling in valleys with mining debris, and for covering streams and disrupting ecosystems.Spoil is placed at the head of a narrow, steep-sided valley or hollow. In preparation for filling this area, vegetation and soil are removed and a rock drain constructed down the middle of the area to be filled, where a natural drainage course previously existed. When the fill is completed, this underdrain will form a continuous water runoff system from the upper end of the valley to the lower end of the fill. Typical head-of-hollow fills are graded and terraced to create permanently stable slopes. Underground mining.
Coal wash plant in,Most coal seams are too deep underground for opencast mining and require underground mining, a method that currently accounts for about 60 percent of world coal production. In deep mining, the method progresses along the seam, while pillars and timber are left standing to support the mine roof.
Once room and pillar mines have been developed to a stopping point (limited by geology, ventilation, or economics), a supplementary version of room and pillar mining, termed second mining or, is commonly started. Miners remove the coal in the pillars, thereby recovering as much coal from the coal seam as possible. A work area involved in pillar extraction is called a pillar section.Modern pillar sections use remote-controlled equipment, including large hydraulic mobile roof-supports, which can prevent cave-ins until the miners and their equipment have left a work area. The mobile roof supports are similar to a large dining-room table, but with hydraulic jacks for legs. After the large pillars of coal have been mined away, the mobile roof support's legs shorten and it is withdrawn to a safe area. The mine roof typically collapses once the mobile roof supports leave an area. Remote Joy HM21 Continuous Miner used undergroundThere are six principal methods of underground mining:.
accounts for about 50 percent of underground production. The longwall shearer has a face of 1,000 feet (300 m) or more. It is a sophisticated machine with a rotating drum that moves mechanically back and forth across a wide coal seam. The loosened coal falls onto an armored chain conveyor or pan line that takes the coal to the conveyor belt for removal from the work area. Longwall systems have their own hydraulic roof supports which advance with the machine as mining progresses. As the longwall mining equipment moves forward, overlying rock that is no longer supported by coal is allowed to fall behind the operation in a controlled manner.
The supports make possible high levels of production and safety. Sensors detect how much coal remains in the seam while robotic controls enhance efficiency. Longwall systems allow a 60-to-100 percent coal recovery rate when surrounding geology allows their use. Once the coal is removed, usually 75 percent of the section, the roof is allowed to collapse in a safe manner. utilizes a Continuous Miner Machine with a large rotating steel drum equipped with tungsten carbide picks that scrape coal from the seam. Operating in a 'room and pillar' (also known as 'bord and pillar') system—where the mine is divided into a series of 20-to-30-foot (5–10 m) 'rooms' or work areas cut into the coalbed—it can mine as much as 14 tons of coal a minute, more than a non-mechanised mine of the 1920s would produce in an entire day.
Continuous miners account for about 45 percent of underground coal production. Transport the removed coal from the seam. Remote-controlled continuous miners are used to work in a variety of difficult seams and conditions, and robotic versions controlled by computers are becoming increasingly common.
Continuous mining is a misnomer, as room and pillar coal mining is very cyclical. In the US, one can generally cut 20 feet (6 meters) (or a bit more with permission) (12 meters or roughly 40 ft in South Africa before the Continuous Miner goes out and the roof is supported by the Roof Bolter), after which, the face has to be serviced, before it can be advanced again. During servicing, the 'continuous' miner moves to another face. Some continuous miners can bolt and rock dust the face (two major components of servicing) while cutting coal, while a trained crew may be able to advance ventilation, to truly earn the 'continuous' label. However, very few mines are able to achieve it. Most continuous mining machines in use in the US lack the ability to bolt and dust.
This may partly be because incorporation of bolting makes the machines wider, and therefore, less maneuverable. consists of coal deposits that are mined by cutting a network of rooms into the coal seam. Pillars of coal are left behind in order to keep up the roof. The pillars can make up to forty percent of the total coal in the seam, however where there was space to leave head and floor coal there is evidence from recent open cast excavations that 18th-century operators used a variety of room and pillar techniques to remove 92 percent of the in situ coal. However, this can be extracted at a later stage ( see ). or conventional mining, is an older practice that uses such as to break up the coal seam, after which the coal is gathered and loaded onto shuttle cars or conveyors for removal to a central loading area. This process consists of a series of operations that begins with “cutting” the coalbed so it will break easily when blasted with explosives.
This type of mining accounts for less than 5 percent of total underground production in the US today., a method currently accounting for less than 1 percent of deep coal production, involves the use of a continuous mining machine with movable roof supports, similar to longwall. The continuous miner shears coal panels 150 to 200 feet (45 to 60 metres) wide and more than a half-mile (1 km) long, having regard to factors such as geological strata. is a method in which the pillars or coal ribs used to hold up the mine roof are extracted; allowing the mine roof to collapse as the mining works back towards the entrance. This is one of the most dangerous forms of mining, owing to imperfect predictability of when the roof will collapse and possibly crush or trap workers in the mine. Production.
Main article:Coal is mined commercially in over 50 countries. Over 7,036 Mt/yr of was produced in 2007, a substantial increase over the previous 25 years.
In 2006, the world production of (lignite) was slightly over 1,000 Mt, with Germany the world's largest brown coal producer at 194.4 Mt, and China second at 100.6 Mt.Coal production has grown fastest in Asia, while Europe has declined. Since 2013, the world coal production is decreasing, -6% in 2016. The top coal mining nations are:2009 estimate of total coal productionCountryProduction3,450 Mt973 Mt557 Mt409 Mt298 Mt252 Mt250 Mt135 Mt101 Mt75 MtMost coal production is used in the country of origin, with around 16 percent of hard coal production being exported.are available in almost every country worldwide, with recoverable reserves in around 70 countries.
At current production levels, coal reserves are estimated to last 147years. However, production levels are by no means level, and are in fact increasing and some estimates are that could arrive in many countries such as China and America by around 2030. Either (1) 'Resources' ('measured' + 'indicated' + 'inferred' = 'resources', and then, a smaller number, often only 10-20% of 'resources', (2) 'Run of Mine' (ROM) reserves, and finally (3) 'marketable reserves', which may be only 60% of ROM reserves.
The standards for reserves are set by stock exchanges, in consultation with industry associations. For example, in countries reserves standards follow the Australasian Joint Ore Reserves Committee Code used by the.Modern mining. Laser profiling of a minesite by a coal miner using a Maptek I-site laser scanner in 2014Technological advancements have made mining today more productive than it has ever been. To keep up with technology and to extract coal as efficiently as possible modern mining personnel must be highly skilled and well trained in the use of complex, instruments and equipment. Many jobs require four-year university degrees. Computer knowledge has also become greatly valued within the industry as most of the machines and safety monitors are computerized.The use of sophisticated sensing equipment to monitor air quality is common and has replaced the use of small animals such as canaries, often referred to as '.In the United States, the increase in technology has significantly decreased the mining workforce.
In 2015 US coal mines had 65,971 employees, the lowest figure since began collecting data in 1978. However, a 2016 study reported that a relatively minor investment would allow most coal workers to retrain for the solar energy industry.
West Virginia, US, 1968.Historically, coal mining has been a very dangerous activity and the list of historical coal is a long one. In the US alone, more than 100,000 coal miners were killed in accidents in the twentieth century, 90 percent of the fatalities occurring in the first half of the century.More than 3,200 died in 1907 alone.Open cut hazards are principally mine wall failures and vehicle collisions; underground mining hazards include suffocation, gas poisoning, roof collapse, and explosions.explosions can trigger the much-more-dangerous explosions, which can engulf an entire pit. Most of these risks can be greatly reduced in modern mines, and multiple fatality incidents are now rare in some parts of the developed world. Modern mining in the US results in approximately 30 deaths per year due to mine accidents.However, in lesser developed countries and some developing countries, many miners continue to die annually, either through direct accidents in coal mines or through adverse health consequences from working under poor conditions., in particular, has the highest number of coal mining related deaths in the world, with official statistics claiming that 6,027 deaths occurred in 2004. To compare, 28 deaths were reported in the US in the same year.
Coal production in China is twice that in the US, while the number of coal miners is around 50 times that of the US, making deaths in coal mines in China 4 times as common per worker (108 times as common per unit output) as in the US.Mine disasters have still occurred in recent years in the US, Examples include the of 2006, and the 2007 mine accident in 's, where nine miners were killed and six entombed. In the decade 2005-2014, US coal mining fatalities averaged 28 per year. The most fatalities during the 2005-2014 decade were 48 in 2010, the year of the in West Virginia, which killed 29 miners. Miners can be regularly monitored for reduced lung function due to coal dust exposure using.Chronic diseases, such as (black lung) were once common in miners, leading to reduced. In some mining countries black lung is still common, with 4,000 new cases of black lung every year in the US (4 percent of workers annually) and 10,000 new cases every year in China (0.2 percent of workers).
A video on the use of roof screens in underground coal minesImprovements in mining methods (e.g. Longwall mining), hazardous gas monitoring (such as or more modern electronic gas monitors), gas drainage, and ventilation have reduced many of the risks of rock falls, explosions, and unhealthy air quality. Gases released during the mining process can be recovered to generate electricity and improve worker safety with.
Another innovation in recent years is the use of, respirators that contain oxygen for situations where mine ventilation is compromised. Statistical analyses performed by the US Department of Labor's (MSHA) show that between 1990 and 2004, the industry cut the rate of injuries by more than half and fatalities by two-thirds. However, according to the, even in 2006, mining remained the second most dangerous occupation in America, when measured. However, these numbers include all mining, with contributing the majority of fatalities; coal mining resulted in only 47 fatalities that year.
Environmental impacts. Environmental activists blocking a coal mine to promoteCoal mining can result in a number of adverse effects on the.Surface mining of coal completely eliminates existing vegetation, destroys the genetic soil profile, displaces or destroys wildlife and habitat, degrades air quality, alters current land uses, and to some extent permanently changes the general topography of the area mined. This often results in a scarred landscape with no scenic value. Of greater concern, the movement, storage, and redistribution of soil during mining can disrupt the community of and consequently processes.
Rehabilitation or reclamation mitigates some of these concerns and is required by US Federal Law, specifically the.Mine dumps could produce which can seep into and, with consequences on and.If underground mine tunnels collapse, they cause of the ground above. Subsidence can damage buildings, and disrupt the flow of streams and rivers by interfering with the natural.Coal production is a major contributor to: burning coal generates large quantities of and mining operations can release, a known, into the atmosphere. The coal mining industry is working to improve its public image. Legality of coal mining A court in Australia has cited climate change in ruling against a new coal mine. Coal mining by country.
Main article:Coal is mined in every state of Australia, but mainly in Queensland, New South Wales and Victoria. It is mostly used to generate electricity, and 75% of annual production is exported, mostly to eastern Asia.In 2007, 428 million tonnes of coal was mined in Australia. In 2007, coal provided about 85% of Australia's electricity production. In fiscal year 2008/09, 487 million tonnes of coal was mined, and 261 million tonnes was exported.
In fiscal year 2013/14, 430.9 million tonnes of coal was mined, and 375.1 million tonnes was exported. In 2013/14, coal provided about 69% of Australia's electricity production.In 2013, Australia was the world's fifth-largest coal producer, after China, the United States, India, and Indonesia. However, in terms of proportion of production exported, Australia is the world's second largest coal exporter, as it exports roughly 73% of its coal production. Indonesia exports about 87% of its coal production. Canada Canada was ranked as the coal producing country in the world in 2010, with a total production of 67.9 million tonnes.
Canada's, the 12th largest in the world, are located largely in the province of.The first coal mines in North America were located in and, mined by French settlers beginning in the late 1600s.

Main article:The is by far the largest producer of coal in the world, producing over 2.8 billion tons of coal in 2007, or approximately 39.8 percent of all coal produced in the world during that year. For comparison, the second largest producer, the United States, produced more than 1.1 billion tons in 2007. An estimated 5 million people work in China's coal-mining industry. As many as 20,000 miners die in accidents each year.
Most Chinese mines are deep underground and do not produce the surface disruption typical of strip mines. Although there is some evidence of of mined land for use as parks, China does not require extensive reclamation and is creating significant acreages of, which is unsuitable for agriculture or other human uses, and inhospitable to indigenous wildlife. Chinese underground mines often experience severe surface (6–12 meters), negatively impacting farmland because it no longer drains well. China uses some subsidence areas for ponds but has more than they need for that purpose. Reclamation of subsided ground is a significant problem in China. Because most Chinese coal is for domestic consumption, and is burned with little or no control equipment, it contributes greatly to visible smoke and severe air pollution in industrial areas using coal for fuel.
China's total energy uses 67% from coal mines.Colombia. Main article:Coal mining in India has a long history of commercial exploitation starting in 1774 with John Sumner and of the in the along the Western bank of. Demand for coal remained low until the introduction of steam locomotives in 1853. After this, production rose to an annual average of 1 Mt and India produced 6.12 Mt per year by 1900 and 18 Mt per year by 1920, following increased demand in the First World War, but went through a slump in the early thirties. The production reached a level of 29 Mt by 1942 and 30 Mt by 1946. After independence, the country embarked upon five-year development plans. At the beginning of the 1st Plan, annual production went up to 33 Mt.
During the 1st Plan period, the need for increasing coal production efficiently by systematic and scientific development of the coal industry was being felt. Setting up the National Coal Development Corporation (NCDC), a Government of India undertaking, in 1956 with the collieries owned by the railways as its nucleus was the first major step towards planned development of Indian Coal Industry. Along with the Singareni Collieries Company Ltd. (SCCL) which was already in operation since 1945 and which became a government company under the control of Government of Andhra Pradesh in 1956, India thus had two Government coal companies in the fifties.
SCCL is now a joint undertaking of Government of Telangana and Government of India.Japan. Main article: Russia Russia ranked as the in 2010, with a total production of 316.9 Mt. Russia has the world's second largest coal reserves. Russia and Norway share the coal resources of the Arctic archipelago of, under the. Spain Spain was ranked as the coal producing country in the world in 2010. The coal miners of Spain were active in the on the Republican side.
In October 1934, in, union miners and others suffered a fifteen-day siege in Oviedo and Gijon. There is a museum dedicated to coal mining in the region of, called.In October 2018, the and Spanish settled an agreement to close ten Spanish coal mines at the end of 2018. The government pre-engaged to spend 250 million Euro to pay for early retirements, occupational retraining and structural change. In 2018, about 2,3 per cent of the electric energy produced in Spain was produced in.
South Africa. Abandoned coal mine in,.In, coal is distributed mainly in the northern area. All of the commercial coal deposits occurred in three coal-bearing formations, which are the Upper, the Middle and the Lower Coal Measures. The Middle Coal Measures was the most important with its wide distribution, great number of coal beds and extensive potential reserves. Taiwan has coal reserves estimated to be 100-180 Mt.
However, coal output had been small, amounting to 6,948 metric tonnes per month from 4 pits before it ceased production effectively in 2000. The abandoned coal mine in, has now turned into the. A view of Murton colliery near, United Kingdom, 1843Before the industrial revolution much of the coal was used near to its production, although there was an active trade along the coast supplying coal to and.Many coalfields were developed in the industrial revolution. The oldest were in and, the of Scotland and the, such as those at. The oldest continuously worked deep-mine in the United Kingdom was in the. This colliery was developed in 1805, and its miners bought it out at the end of the 20th century, to prevent it from being closed.
Tower Colliery was finally closed on 25 January 2008.The United Kingdom was ranked as the coal producing country in the world in 2010, with a total production of 18.2 million tonnes. Coal mining in the United Kingdom probably dates to; coal production increased significantly during the in the 19th century and peaked during. As a result of its long history with coal Britain's economically recoverable coal reserves have decreased, and more than twice as much coal is now imported than produced. United States. Further information:Coal was mined in America in the early 18th century, and commercial mining started around 1730 in.The American share of world coal production remained steady at about 20 percent from 1980 to 2005, at about 1 billion per year. The United States was ranked as the highest coal producing country in the world in 2010, and possesses the largest in the world. In 2008 then- stated that coal was the most reliable source of electricity.
However, in 2011 President said that the US should rely more on 'clean' sources of energy that emit lower or no pollution. For a time, while domestic coal consumption for electric power was being displaced by natural gas, exports were increasing. US net coal exports increased ninefold from 2006 to 2012, peaked at 117 million short tons in 2012, then declined to 63 million tons in 2015.
In 2015, 60% of net US exports went to Europe, 27% to Asia.US coal production increasingly comes from strip mines in the western United States, such as from the in Wyoming and Montana.Coal has come under continued price pressure from and sources, which has resulted in a rapid decline of coal in the U.S. And several notable bankruptcies including. On 13 April 2016 it reported, that its revenue had reduced by 17 percent as coal prices fell and that it had lost two billion dollars the previous year. It then filed on 13 April 2016.
