摘　　要：煤矿矸石山自燃是导致矸石山自燃爆炸灾害事故和造成矿区周围环境污染的主要原因。将矸石山看作一大体积多孔介质,运用多孔介质流体渗流理论并结合达西定律和渗流连续性方程,建立了煤矿矸石山自然发火的数学模型,并在此基础上对新建煤矿运输区矸石山内部漏风风流的流动规律进行了研究,提出了矸石山自然发火的防治途径。Spontaneous combustion of waste dump is the primary reason resulting in the spontaneous combustion explosion accident of waste dump and the pollution of ambient environment In this paper, a mathematical model of spontaneous combustion of waste dump was established by regarding the waste dump as a big bulk porous medium and using the seepage theory of porous medium, the Darcy law and the continuity equation of seepage. On this base, study was made the flow pattern of air leakage in the waste dump of transport district in Xinjian Coal Mine and the preventive and control measures for spontaneous combustion of waste dump were put forward.
