任楼煤矿隐伏导水陷落柱的快速判识与探查

1996年任楼煤矿首采面曾因隐伏导水陷落柱突水，引发淹井灾害，造成3．5亿元的重大经济损失。治水复矿后，1999年又在7218工作面机巷迎头出现淋水，初始水量不大，但依据水温、水质快速判识突水通道是隐伏导水陷落柱，运用物探和钻探相结合的综合探查方法确定了陷落柱位置，为地面布孔注浆彻底封堵陷落柱提供了保证，避免了一次重大突水淹井事故。

Quick recognition and detection of hidden conducting karst collapse column in Renlou coal mine

Because of water outburst by hidden conducting Karst collapse column at the mining area of Renlou coal mine, the flood was caused in 1996, which causes losses up to 3.5 hundred million yuan. In 1999 when reconstruction, the dripping appeared on the tunnel of 7_218 work face. Though initially flow was not much heavy,the hidden conducting Karst collapse column was still recognized by the temperature and property of the water. Then the position of the column had been determined with synthetic detecting methods, which enabled it fully filled from the surface and avoided a terrible accident.
