Electrical Hazards in Underground Bituminous Coal Mines
An investigation of 1404 injuries related to electricity in underground bituminous coal mines revealed that more than 96 percent of all electrical accidents were caused by (1) arcs resulting in burns, (2) electrically generated heat resulting in burns and scalds, and (3) electrocution and shock. Data analysis indicates that a reduction in electrical accidents is immediately possible by reducing defective splices and insulation breaks and by proper placement of trolley poles. Sixty-six percent of the mine fires investigated by the Bureau of Mines through 1972 and 21 percent of all methane ignitions can be attributed to electrical ignition sources and inadequate design of electrical equipment used in the mining environment.
