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。
南莊煤礦15＃煤層採用綜放開採，綜放工作麵在初期開採過程中，由于受上覆臨近煤巖層瓦斯湧齣以及綜放麵初採不放煤的影響，導緻工作麵初採期間瓦斯湧齣異常。經過不斷研究和探索，南莊煤礦採用初採高抽巷和鑽孔抽放兩類三種治理方式，經8816和8818等工作麵應用，有效治理瞭工作麵初採期間的瓦斯湧齣異常，取得瞭良好的效果。

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.
