摘　　要：西铭矿针对开采设计、装备、能力及瓦斯涌出规律的变化,制定了瓦斯治理措施,采用“本煤层水力割缝钻孔抽采+底抽巷下邻近层CO_(2)预裂抽采+顶板高位走向大孔径长钻孔抽采+顶板裂隙高位走向大孔径抽采+瓦斯治理巷超大孔径煤岩柱钻孔抽采”相结合的立体式、分源式、精准式综合瓦斯治理措施,实现了高瓦斯矿井在低瓦斯状态下开采的目的。According to the changes of mining design,equipment,capacity and gas emission law,Ximing mine has formulated gas control measures,which adopts the the combined three-dimensional,source separation and accurate comprehensive gas control measures of"hydraulic slotted drilling drainage in this coal seam+CO2 pre-splitting drainage in the adjacent layer under the bottom drainage roadway+large aperture long drilling drainage in the high direction of the roof+large aperture drainage in the high direction of the roof fissure+large aperture drainage in the high direction of the roof+large aperture coal and rock pillar drilling drainage in the gas control roadway",to realize the purpose of mining high gas mines in low gas state.
