摘　　要：通过采用采面上隅角抽采、采前预抽、采空区卸压抽采、高位抽采巷抽采、掘进预抽、下分层拦截预抽、区域预抽等抽采方法对大佛寺煤矿41104工作面瓦斯进行了综合治理,建立了一套适合于大佛寺煤矿煤层赋存条件及开采条件的瓦斯治理技术。The comprehensive gas control was carried out at No. 41104 mining face of Dafosi Coal Mine, via gas drainage in upper corner, predrainage be{ore mining, gas drainage by pressure release in goaf, gas drainage from high-level roadway, predrainage during tunnelling, lower slice intercepting predrainage, and regional gas predrainage. A set of gas control technology suitable for occurrence conditions of coal seam and mining conditions of Dafosi Coal Mine was established.
