摘要
煤矿井下炮掘巷道施工条件复杂,特别是爆破施工系统巷时,由于施工位置及机械设备所限,严重降低了巷道施工过程中排矸效率,制约了掘进速度。本文通过同煤大唐塔山煤矿为例浅谈炮掘巷道复杂条件下提高排矸率优化设计。
The construction condition of coal mine blasting excavation is complex, due to the limitation of the location of construction machinery and equipment, which severely reduced the construction process of roadway ranked gangue efficiency, and control the tunneling speed. Taking Tashan coal mine as an example, discussed the optimal design improve the discharge rate of coal gangue under complex condition.
