Coal mining - Wikipedia

CachedMethods of ExtractionProductionModern MiningSafetyCoal Mining by CountryExternal LinksCoal extraction methods vary depending on whether the mine is an underground mine or a surface also called open cast mine. Additionally coal seam thickness and geology are factors in selection of a mining method. The most economical method of coal extraction for surface mines is the electric shovel or drag line. The most economical form of underground mining is the long wall, which is a shear blade that runs along sections of the coal seam. Many coals extracted from both surface and underground mines require washing in a coal preparation plant. Technical and economic feasibility are evaluated based on the following: regional geological conditions; overburdencharacteristics; coal seam continuity, thickness, structure, quality, and depth; strength of materials above and below the seam for roof and floor conditions; topography especially altitude and slope ; climate; land ownership as it affects the availability of land for mining and access; surface drainage patterns; groundwater c... See full list on Coal is mined commercially in over 50 countries. 7,921 Mt of coal were produced in 2019, a 70% increase over the 20 years since 1999. In 2018, the world production of brown coal lignite was 803.2 Mt, with Germany the world& 39;s largest producer at 166.3 Mt. China is most likely the second largest producer and consumer of lignite globally although specific lignite production data is not made available. Coal production has grown fastest in Asia, while Europe has declined. Since 2011, world coal production has been stable, with decreases in Europe and USA offset by increases from China, Indonesia and Australia.The top coal mining nations are: Most coal production is used in the country of origin, with around 16 percent of hard coal production being exported. citation needed See full list on Technological advancements have made coal 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, state-of-the-art 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. citation needed The use of sophisti ed sensing equipment to monitor air quality is common and has replaced the use of small animals such as canaries, often referred to as "miner& 39;s canaries". In the United States, the increase in technology has significantly decreased the mining workforce. in 2015 US coal mines had 65,971 employees, the Seven Trustt figure since EIA 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 en...
