way we cost underground coal mining systems by G.H. Lind* Synopsis This paper discusses the traditional costing approach currently used in the underground coal mining industry. Activity Based Costing (ABC) is identified as being a potentially more effective manner in which to cost underground coal mining systems. With
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 room and pillar or bord and pillar method progresses along the seam, while pillars and timber are left standing to support the mine roof.

15-5-2014The Benxihu colliery disaster in China cost 1,549 lives and is believed to be the worst coal mining disaster ever. The tragedy occurred on 26 April 1942 in the Honkeiko coal mine, located near Benxi in the Liaoning province of China. The fatal explosion of the underground coal mine was caused by a mixture of gas and coal dust.
COAL MINING 1 Underground M: Since 1900, accidents have killed over 100,000 U.S. miners; over 200,000 have died from black lung disease. E: These deaths and illnesses are re!ected in wages and workers' comp, costs considered internal to the coal industry, but long-term sup-port often depends on state and federal funds.
Coal Mining Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. Surface Mining If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.
