| 摘 要： | 煤矿掘进过程中揭露了小断裂,断裂活化后,煤层下覆岩溶水涌入;矿井突水导致了龙洞坝泉暂时性断流.介绍了突水治理方案：采用物探方法寻找突水井巷,用“地表钻孔注砼法”封堵突水段井巷.该方案能彻底封堵本次突水的导水断裂和龙洞坝泉的水力联系,使龙洞坝泉涌水不会再受本次突水影响,同时,也能解除煤矿受本次突水的危害,为煤矿下一步的恢复工作奠定基础.

| Abstract: | A small fault is exposed in the exploitation of coal deposit, the karst water under the coal bed ab- ruptly wells, which causes the temporary cease of Longdongba spring. In this paper, we show the scheme of welling control： the geophysical exploration method used in searching for the welling tunnel, blockade of welling tunnel section with ＂surface drilling hole concreting method＂ . This method can thoroughly blockade the connection of water channel fault of this welling to the Longdongba spring, so the welling of Longdongba spring isn＇ t influ- enced by this welling again, in the meantime, which also can release the damage of this welling to the coal deposit in order to further recover the production of coal mine. |
