摘　　要：分析了“先抽后采”概念的内涵及对煤矿瓦斯治理的作用,在研究煤矿煤层瓦斯赋存特点的基础上,综合分析了煤矿瓦斯抽采方法,结合煤矿瓦斯治理的实例和煤矿重特大瓦斯事故案例,对我国煤矿瓦斯治理提出了以下建议,即在有条件的情况下尽可能优先采用区域性瓦斯治理方法,强突出危险煤层和超大井型高瓦斯矿井必须采用区域性瓦斯治理方法.In this paper, we analyzed the concept of ＂draining gas before coal mining＂ and its effectiveness of gas control in mines. Based on gas storage characteristic of coal seams, a gas ex traction method used in coal mines is discussed. According to some examples of gas control and some cases of major gas accident, we suggest that, if the condition permit, the regional gas control should be the first choice, and, for those coal seams highly dangerous in gas burst and those supper-large coal mines with a high gas content, the regional gas control must be used.
