摘要
煤炭自燃严重制约着矿井的安全生产。采空区自燃约占自燃事故的三分之一,治理起来难度大,投资费用高。本文通过对潘西煤矿十九层煤自燃发火机理和防治技术的研究,总结出困难条件下预防采空区自燃的方法,供其它相似矿井参考借鉴。
Self- burning of coal seriously restricts the safety production of coal mine. The self- burning of the waste area takes up about one - third of the self- burning accidents. It＇ s difficuh to harness and invest cost is large. This paper summarizes the method of preventing self- burning in goaf under difficuh conditions by the study of firing mechanism and control technique of self- burning on 19th coal layer of Panxi Coal Mine, and provides a reference for the similar wells.
