摘要
为了防治煤矿回采工作面采空区自然发火,实现安全生产,本文通过对注氮原理分析,对回采工作面采空区注氮防灭火技术各项参数不断分析改进,取得了较好效果,并在开滦集团各矿井进行推广应用。
In order to prevent spontaneous combustion in working face goaf and to achieve work safety, based on the analysis of the principle of nitrogen injection, the parameters of nitrogen injection technology for fire prevention in working face goal are improved gradually in the coal mines of Kailuan Group. , which achieves good results and has wide applications
