有自燃发火倾向的深水平煤层开采是比较复杂和危险的,因为直接靠近内燃火源附近将产生甲烷、一氧化碳、氢和其它碳氢化合物组成的可燃爆炸性的混合气体,会引起内因火灾。 可通过先创造安全的隔离条件,然后再进行隔离作业途经改变开采的危险局面。发火巷道在隔离之前,须对火源采取处理措施。 不久以前,预防和扑灭火灾的唯一措施仍是往采空区和巷道内灌注泥浆。 但是,当火区周围巷道内的瓦斯达到爆炸浓度时。灌注泥浆的效果在大多数情况 Deep horizontal coal mining with spontaneous firing propensity is more complicated and dangerous because direct combustion near the internal combustion sources will produce a flammable and explosive mixture of methane, carbon monoxide, hydrogen and other hydrocarbons that can cause internal fires. This can be done by first creating a safe separation condition and then changing the mining operation by doing the isolation work. Fire tunnel before isolation, to take measures to deal with the fire. Not long ago, the only measure to prevent and extinguish a fire still was to pour mud into goafs and tunnels. However, when the gas in the tunnel around the fire area reaches the explosive concentration. The effect of pouring mud in most cases
