| 摘 要： | 新安煤矿井下2#水文孔硐室出水原因系水文孔漏水所致。质量隐患、奥灰高水压的长期作用、水文孔承受水压的升降变化等,导致井下2#水文孔套管断裂错位,其环状间隙向上渗水,奥灰高水压的强大作用下又造成水泥地坪错断裂缝,从而导致水文孔硐室突然出水。

| Abstract: | The water bursting of No.2 underground hydrogeological hole cavity was caused by the water leakage of the hydrogeological hole. The pipe of the hydrogeological hole was faulted by it's unqualification, the high pressure of Ordovician karst water for a long time, and the changes of the hydraulic pressure that the hole beared, then the karst water leaked from the circular gap of the hole, the cement floor was damaged by the strong hydraulic pressure, the water bursting caused finally in the hydrogeological hole cavity. |
