Abstract

Of safety technologies of coal mines summarized as a handbook, described is the safety technology on spontaneous combustion. The spontaneous combustion of coal is caused by storage of oxidation heat, but real factors causing the combustion are complicated. Immediate detection by a centralized monitoring sensor of generated gases (CO, CH{sub 4}, air leakage), temperatures and odors are contributed to reduction of accidents. The spontaneous combustion is apt to occur in mine roadway and abandoned shafts and by disturbance and degradation of the remaining coal left alone and by air leakage. It is important to shield a ventilation current and secure sealing after mining. The fly ash (FA) method in which FA slurry is streamed and transported for filling-up brought an ennovation to measures against spontaneous combustion. As a direct fire-fighting method, the following interception of fire source is cited: watering pipes, boring water-pouring, milk state liquid injection, foam-plug, FA-plug. As an indirect fire-fighting method, the following are cited: a method in which the mine roadway is lined and the inside of the lining is filled with FA, etc. for sealing, a sealing dam construction method. Some accidents at coal mines and prevention measures are also explained. 49 refs., 45 figs.,  More>>
