摘要
目前由于矿井巷道掘进效率普遍不高,从而极大地影响了矿井生产的正常接替。文中通过优化爆破参数,提高了岩巷掘进的爆破效率,最终提高了巷道掘进速度。
Mine tunneling efficiency is generally not very high, which will have a tremendous impact on normal replacement of mining. By optimizing blasting parameters, the blasting efficiency of mine tunnel excavation is improved. The speed of tunnel excavation is ultimately increased.
