正利煤矿14^(-1)102孤岛工作面瓦斯综合治理技术研究

Study on Gas Comprehensive Control Technology of 14^(-1)102 Isolated Island Working Face in Zhengli Coal Mine

为保证工作面安全高效开采,在分析正利煤矿14^(-1)102孤岛综采面瓦斯来源和瓦斯涌出规律的基础上,采用高位裂隙带钻孔抽采、采空区插管抽采、强制放顶、邻近采空区瓦斯抽采与风排瓦斯相结合的瓦斯综合治理措施,能够有效解决孤岛工作面瓦斯超限问题,确保工作面正常回采。

In order to ensure the safe and efficient mining of the working face,based on the analysis of the gas source and gas emission law of 14^(-1)102 isolated island fully mechanized mining face in Zhengli Coal Mine,the comprehensive gas control measures of high fracture zone drilling drainage,goaf intubation drainage,forced caving,gas drainage in adjacent goaf and air drainage gas are adopted,which can effectively solve the problem of gas overrun in isolated island working face and ensure the normal mining of working face.
