煤矿矸石山灭火技术的研究与应用

Research and application of coal-mine waste rock fire extinguishing technique

将适当比例的黄土、粉煤灰制成的浆液,由机械设备灌注自燃矸石山的深部,通过对自燃矸石的“隔氧”和“降温”作用,使自燃的矸石山熄灭。本文结合平煤四矿自燃矸石山治理实例,证明了该技术是治理自燃矸石山的一种快速、经济、有效的好方法。

Affuse the serum, consisting of loess and powder coal ash in a certain proportion, into the depth of self-ignite waste-rock jebel by using mechanical equipment, and through off-oxegen and cooling to extinguish the self-igniting waste rock jebel. This technology proved to be a kind of rapid, economical and effective method.
