摘要
根据开采实际情况,工作面沿空机巷与采区集运巷的连接通常为S弯,造成设备、人员的投入较大,能源消耗较多,本工作面采用了工作面沿空机巷与采区集运巷直巷连接的施工方案,并通过特殊施工方法对老巷进行处理及对大断面控制,在确保安全的前提下优化了运输系统,同时产生了较大的经济效益。
According to the mining actual situation, the connection of mechanized roadway along goal in working face and central transportation roadway in mining area is generally S shape, which increases the cost of equipment and human resources and energy consumption. The straightway connection is used to connect the mechanized roadway along goaf in working face and central transportation roadway in mining area. Along with the special construction to treat the old tunnel and control the large section, the transportation system is optimized based on the safety. The economic benefit is promoted at the same time.
