摘　　要：本文针对塔山矿综放工作面以顶板高抽巷封闭抽放为主的瓦斯治理方法中存在的问题,结合一盘区地质条件及瓦斯涌出特点,提出了利用开采保护层的方法预先释放一部分主采煤层瓦斯,降低工作面生产期间的绝对瓦斯涌出量,从而降低顶板高抽巷抽放期间的瓦斯浓度,解决顶板高抽巷封闭抽放偏高的问题,并通过在8108工作面进行试验,证明了这一方法的有效性。In view of the problems existing in the gas drainage method in the fully mechanized top-coal caving face of the Tashan Mine, which is based on the closed drainage of the high extraction roadway in the roof, combined with the geological conditions and the characteristics of the gas emission in the one area, the method of mini To reduce the gas concentration during the pumping of the roof, and to solve the problem of high ng the protective layer closed drainage in the high-suction roadway of the roof, and to solve the problem of high gas drainage in 8108 The test of the working face proves the effectiveness of this method.
