摘要
针对高庄煤矿3_(上)1104回风巷为沿空掘巷,巷道掘进期间受3_(上)1102老空水威胁,掘进开采存在严重的水患安全问题,采用超前打设疏水孔的方案来治理老空水威胁,对巷道采用调向增大护巷煤柱厚度等措施实现巷道安全快速掘进,探放水期间无淹巷情况发生,探放水后巷道顶板和上帮无淋水现象发生。
In view of the fact that the No.3_(upper) 1104 return air roadway in Gaozhuang Coal Mine is driven along the goaf,the roadway is threatened by No.3_(upper) 1102 old empty water during tunneling,and there is a serious flood safety problem in tunneling,so the scheme of setting drainage holes in advance is adopted to control the threat of old empty water.The roadway adopts measures such as adjusting direction to increase the thickness of coal pillar to realize safe and rapid tunneling,no flooding occurs during water exploration and discharge,and no watering occurs in the roof and upper side of the roadway after water exploration and discharge.
