| 摘 要： | 南庄煤矿15#煤层采用综放开采,综放工作面在初期开采过程中,由于受上覆临近煤岩层瓦斯涌出以及综放面初采不放煤的影响,导致工作面初采期间瓦斯涌出异常。经过不断研究和探索,南庄煤矿采用初采高抽巷和钻孔抽放两类三种治理方式,经8816和8818等工作面应用,有效治理了工作面初采期间的瓦斯涌出异常,取得了良好的效果。

| Abstract: | Gas emission is high at coal seam 15 , Nanzhuang coal mine.In the first stage of fully mechanized mining, gas emission is high , which is ascribed to two reasons：first, the gas transmission from over layers of coal and rock was active , second , the fully mechanized caving face doesn ’ t cave at the first stage.Study and application on the high gas emission have been carried out in the Nanzhuang coal mine .Two types of technolo-gy, namely high drainage roadway and borehole gas drainage came into being , based on which , the high gas emission was controlled. |

| Keywords: | fully mechanized coal caving face gas abnormity mining at the first stoge high drainage roadway borehole gas drainage |
