随着矿井生产不断向深部开拓延伸,矿井水害威胁越来越大。应用传统的巷道掘进工艺进行掘进作业时,探放水期间巷道掘进速度慢,掘进等待时间长,进而造成矿井采掘衔接紧张被动局面,严重制约了矿井的安全高效生产。 With the continuous expansion of mine production to the depth, the threat of mine water damage is increasing. When using the traditional tunneling technology for tunneling operation, the tunneling speed is slow and the waiting time for tunneling is long during the exploration and discharge, which leads to the tight coordination of mine excavation and seriously restricts the safe and efficient production of the mine.
