摘要
淮南矿业集团顾桥煤矿1112(1)轨道顺槽为沿空掘进巷道,掘进期间的瓦斯涌出量大,通过采用均压法、抽采法、喷注浆等采空区瓦斯综合治理措施,最终有效解决了采空区瓦斯对巷道掘进的安全威胁,为沿空巷道掘进期间瓦斯治理提供较好地借鉴。
The 1112 （1） the orbital gateway in Gu Qiao coal mine, is the roadway drivage along goaf, and quantities of gas is emitted during excavation. However, by means of such comprehensive management measures as equalizing pressing method, extraction method, jet grouting, the security threats to goaf roadway drivage is ultimately solved, which provide good reference of gas control during drivage along the empty roadway.
