Abstract:

Most coal is capable of self-igniting when placed under certain conditions. This phenomenon is called endogenous fire. The basic cause of coal burning is the oxidation of coal that generates heat, which accumulates over long periods of time with no place to escape, which increases the critical temperature and creates the phenomenon. burning in coal. This is a very dangerous phenomenon in mining pits. Fire products produce more toxic gases, especially CO. It can also be a source of fires caused by methane and coal dust. Coal burning is a very interesting issue in coal mining. When self-incineration occurs, the mine must cease to operate, with significant social and economic losses and, most importantly, a loss of safety in coal mining. The thickness of the coal layer is very different (average thickness is 3.0m, thickness 6.2m), average slope is 50o, direct stone is clay, clay thick 0,2m-:-1.3m easily collapsed. Therefore, it is difficult to apply technology exploited using 2ANSH anti-tank rig. On the other hand, the digging along the +30 ramp caused CO accident as a sign of internal fire. The company has stopped exploiting and preparing for this area
