张双楼煤矿大倾角综采工作面拆除工艺实践

Practice of demolition technology in fully-mechanized working face with large dip angle in Zhangshuanglou Coal Mine

张双楼煤矿大倾角条件下采用下行通风,邻架操作,安装大功率回柱机,工作面内设置掩体拆除工艺,仅用21 d就完成拆除工作,实现了安全生产,对类似矿井具有借鉴作用。

The downward ventilation,operation of adjacent support,installation of high-power pillar return machine,and bunker demolition technology in working face were used in the condition of large dip angle in Zhangshuanglou Coal Mine.The demolition work of the working face was completed in only 21 days,which has realized the safety production and has a reference role for similar mines.
