摘要
为保障工作面能够安全有序的开采,针对胡底煤矿高瓦斯条件的现状,在1303(上)采煤工作面采用“千米高位钻孔+普钻中位孔+采空区埋管抽放”的模式治理采空区瓦斯,确定1303工作面高位孔设计层位为18~21 m,抽采效果较好。1303(上)综采工作面瓦斯治理模式的成功应用将为胡底煤业采面采空区瓦斯治理保障措施和治理效果提供坚实基础和技术支持。
To ensure the safe and orderly mining of the working face,in view of the current situation of high gas conditions in Hudi Colliery,"kilometer high drilling+ordinary drilling middle hole+underground pipe extraction in the goaf"is used to control the gas in the goaf of 1303(upper)coal mining face,and the design horizon of the high-level hole in the 1303 working face is determined to be 18-21 m,which proves good drainage effect and will provide a solid foundation and technical support for gas treatment safeguard measures and treatment effects in the goaf of the Hudi Coal Industry.
