摘要
2004年9月25日牛儿庄矿发生了突水量达108m3m/in的特大溃水事故,直接威胁了相邻两个矿井的安全生产。通过调查分析认为此次突水水源为煤系基底奥陶系灰岩含水层,是位于牛儿庄矿井田范围内的永顺煤矿开采下架煤层突水而造成的。在突水通道、动水力等条件复杂的情况下,经过三个阶段的水害治理,效果达100%,为类似堵水治理工程提供了有益的借鉴。
In September 25th, 2004, extraordinary serious 108 m^3/min water flooding happened in Niuerzhuang coalmine and directly threatening safety production of two neighboring coalmines.Through investigation and analysis confirmed that the flooding water source was Ordovician limestone aquifer as the basement of coal measures. The immediate causation was a water irruption caused by the mining of Xiajia coal seam by the Yongshun coalmine within the Niuerzhuang minefield. Under the complicated water inrush channels and hydrodynamic condition, finally 100% successfully fulfilled through three stages of water flooding governing. It is a useful reference for similar water blocking projects.
