摘要
鸡东煤矿在回采东一采区28#右三采煤工作面时,采用施工煤层底板瓦斯抽排钻场进行抽放瓦斯,有效地解决了28#以下煤层瓦斯涌出造成的瓦斯超限问题,为该矿今后综合治理高瓦斯涌出的采区提供了依据。
When Jidong Coal Mine Mined at the right NO.3 coal face in East NO.1 mining area,the gas drainage drill field at the coal floor was used for gas drainage.The gas gauge problem caused by gas emission in NO.28 coal seam below was effectively solved.The basis is provided for the gas management in the mining area of high gas emission in the coal mine in future.
