摘要
采煤工作面超前支护是为了确保工作面上下出口的畅通而采取的特殊加强支护。《煤矿安全规程》规定:采煤工作面必须保持至少2个畅通的安全出口,所有安全出口与巷道连接处超前压力影响范围内必须加强支护。本文介绍了泉店煤矿联合布置工作面应用U型钢组合梁超前支护形式的成功实践,以期为类似地质条件下煤层开采提供经验和借鉴。
Advanced support at coal face is a kind of special reinforced support which can make the upper and lower exits of working face unbloeked. According to Coal Mine Safety Regulation, there must be at least 2 unblocked safety exits, and reinforced support is needed within the influenced scope of advanced pressure existing at all junction sites of safety exits and roadways. This article introduced the successful practice of U-steel composite beam applied in combined layout working face in Quandian Coal Mine,which can provide experience and use reference for coal mining under similar geological conditions.
