Coal mining industry primarily covers mining of bituminous, anthracite, and lignite coal by underground mining, strip mining, culm bank mining, and other surface mining techniques. It also includes the development of coal mine sites, and improvement of coal, including cleaning, washing, screening, and sizing of coal.
The top five companies covered are Coal India Limited, ShenHua Group, BHP Billiton Ltd., China Coal Energy Co Ltd. and Anglo American plc. Coal India Limited was the largest competitor in the coal, lignite, and anthracite mining market in 2017.
The countries covered are USA, China, Germany, Brazil, Japan, UK, Spain, Russia, France, Australia, Italy, India and rest of the world.
The global coal, lignite, and anthracite mining market was valued at around $850 billion in 2017. Asia Pacific was the largest region in the coal, lignite, and anthracite mining market in 2017, accounting for more than 70% market share. China was the largest country in the market in 2017, accounting for nearly 55% market share.
Coal mines are prone to hazards and mining companies are increasingly focusing on technologies to prevent accidents and improve the safety of miners. Government regulations, and health and safety standards developed by international mining groups also promote efficient safety practices. Some of the reasons for the occurrence of accidents in mining include ineffective drilling, blasting, loading and hauling, leaking out of poisonous methane gas, coal dust, and machinery collisions. Sensor-based methane detectors use RFID technology to monitor and control the level of methane which can cause explosions. GE’s CoalPlus technology helps in reducing coal dust in mining operations by up to 90%.
The coal, lignite, and anthracite mining market is segmented into coal mining, lignite mining and anthracite mining.
Coal Mining includes the sub sections bituminous coal surface mining and bituminous coal underground mining.
Lignite is the lowest quality coal with low carbon content of 25-35%, moisture content of 20-40%, and heating value of 4000 to 8300 BTU per pound.
Anthracite has the highest carbon content up to 85-90% and low moisture content of 5-15%. It has the highest heating value of 13000 to 15000 BTU per pound.
