摘　　要：为了提升煤矿开采的安全性,以W煤矿5号工作面为例,分别模拟分析了单一抽采方式和联合抽采方式条件下采空区漏风流和瓦斯分布特征,确定出最佳的瓦斯抽采工艺方案,开展了一种煤矿高瓦斯易自燃工作面采空区瓦斯抽采工艺优化方法研究。通过工业性试验,对该瓦斯抽采工艺实际应用效果予以验证,通过验证可知:W煤矿5号工作面开采过程中,最佳瓦斯抽采方式为高位钻孔联合高位埋管。In order to improve the safety of coal mining,taking the No.5 working face of W coal mine as an example,the characteristics of gas leakage and gas distribution in goaf under single and combined extraction methods were simulated and analyzed,and the optimal gas extraction process plan was determined.A study was conducted on the optimization method of gas extraction process in goaf of coal mine high gas prone to spontaneous combustion working face.Through industrial experiments,the practical application effect of the gas extraction process was verified.It was found that the optimal gas extraction method during the mining process of the No.5 working face in W coal mine is high-level drilling combined with high-level buried pipes.
