摘　　要：贵州西部矿区井下瓦斯抽采难度大、随着煤炭开采的不断深入,瓦斯问题导致煤炭生产采掘接续矛盾突出。在三区联动瓦斯治理规划下,针对规划区瓦斯超前治理,新田煤矿在二采区进行了2口地面瓦斯抽采水平井的工程实践。结果表明,通过地面抽采能够有效治理区域条带瓦斯问题,降低井下瓦斯治理难度和缩短治理周期。Underground gas extraction in the western mining area of Guizhou is difficult.The gas problem has led to prominent contradictions in coal production and mining with the deepening of coal mining.Under gas treatment plan of the joint operation within the three regions,the engineering practice of two surface gas extraction horizontal wells was carried out in the second mining area of xintian coal mine for the advanced treatment of gas in the planning area.The results show that the regional strip gas problem can be effectively controlled by surface gas extraction,reducing the difficulty of underground gas treatment and shortening the underground drilling treatment time.
