城郊煤矿北翼轨道大巷快速施工

The speedy drivage of the north wing double-track haulage roadway of Chengjiao coal mine

介绍了 2 0 0 0年城郊煤矿北翼轨道大巷快速施工情况及施工方案、施工方法 ,阐述了全断面光面爆破、分次起爆、一次成巷、锚网喷和锚网喷加钢棚联合支护以及相应的辅助系统等快速施工技术 ,指出了提高炮眼利用率和正规循环率是实现快速施工的根本途径 ,提出了需改进的问题 ,并进行了分析、总结 。

The schema and the method of speedy drivage of the north wing double*.track haulage roadway of Chengjiao coal mine in 2000 are introduced.It has discussed the speedy drivage technology,such as stage initiation of full*.face smooth blasting and completion of drifting in a single stage,combined support by shotcrete and bolting wire mesh with shotcrete and bolting wire mesh set by steel,related auxiliary system,etc.It is considered that improving blast hole utilization rate and regular cycle rate are fundamental means of the realization of speedy drivage.Some problems proposed should be solved,and some analysis and summary have been made.
