Abstract

Of safety technologies of coal mines summarized as a handbook, described is the safety technology on gas{center_dot}coal dust explosions. Reaction process of the explosion is complicated, and for prevention of explosions, it is necessary not to make explosion limit concentration atmospheres of flammable gases (mostly methane) and coal dust and not to give ignition source energy to them. There are various ignition sources such as blasting, electric spark, static electricity, spontaneous fire, mine fire, friction spark. Ventilation is made as measures against methane gas. Measures against coal dust are prevention of coal dust production, cleaning and removal of sedimentary coal dust, inactivation of coal dust and removal of fire source causing explosion. Measures for prevention of explosion propagation are taken just in case of explosion: rock dust barrier, water barrier, auto water curtain, dense rock dust zones. Some explosion prevention technologies in site and some accidents happened are explained. Furthermore, safety standards are established according to mine safety laws and regulations. 69 refs., 49 figs., 20 tabs.
