| Abstract: | A groundwater inrush occurred with water amount reached 32 970 m3/ h at- 2 10 m North Main Tunnel in Guojiazhuang Coal Mine of Feicheng Mining Area.The geological structures are complicated near the water inrush point,and different aquifers contact each other.The severe inrush resulted from confined water gushing into tunnel through weak fractures. |
