摘要: 某矿副斜井掘进断面积达到22.9 m2,为提高掘进速度,采用了2台掘进机同时掘进,掘出2排锚杆间距后及时进行临时锚杆支护的工艺。合理安排、利用了工时,使工人和掘进机的功效达到了最优化,有效提高了斜井掘进速度。Abstract: The tunneling section of auxiliary inclined shaft in a coal mine reached 22.9 m2,in order to improve the tunneling speed,two sets of roadheader were used to excavate at the same time,and the process of carring out the temporary bolt after digging out two rows of bolt spacing was used.It reasonably arranged and used the working hours,the efficacy of workers and roadheaders reached the best and effectively improved the tunneling speed of inclined shaft.
