工作面大断面切眼一次成巷综掘施工工艺探究与实践

Discussion and practice of working face large section cut eye once-tunneling fully mechanized mining technology

梧桐庄矿182811工作面切眼净宽6 m,长度216 m,采用综掘施工大断面切眼一次成巷,出煤系统由传统铺设3~4部SGB-620/40T型号刮板输送机接力运输更改为铺设一部简易胶带输送机出煤,提高了掘进效率,节省了支护材料费用和用工,为该矿大断面切眼综掘一次成巷施工积累了经验。

182811 working face of Wutongzhuang Mine, cut eye with net width 6 m, length 216 m, fully mechanized mining large section cut eye one-tunneling was adopted, the coal output system changed from 3 ~4 SGB-620/40 T scraper conveyer to one Belt conveyor, which improved mining efficiency, saved support cost and labor, which provided experience for large section cut eye fully mechanized mining once-tunneling of the mine.
