摘要
针对岩巷炮掘施工速度较慢的难题,以刘庄煤矿131301瓦斯抽排巷为例,通过引进先进的配套设备及机械化作业线,并制定一系列的岩巷快速成巷措施,实现了高抽巷的快速掘进,平均进尺7.5 m/d,较炮掘工作面快3-4 m/d。
Aiming Takes 131301 gas at the problem of the slow excavation speed of digging and blasting in rock tunnel, drainage roadway of Liuzhuang coal mine as an example. Through the introduction of advanced equipment and machinery operation line and formulating a series of measures for the quick road-made of rock tunnel,and the rapid excavation of high drainge roadway is realized. The average daily footage is 7.5 meters,which is faster than blast mining work-face, the difference is 3-4 m/d.
