摘　　要：铜仁汞矿属于高水头裂隙水充水矿床,矿山基建过程中断层破碎带突水造成淹井事故.为解决矿山基建期的水害问题,采用TSP202超前工程水文地质预报系统,系统掌握了掌子面前方巷道围岩的工程水文地质条件后,采用帷幕注浆技术,在巷道作业面布设一定数量的超前帷幕注浆孔,通过注浆在巷道的周边形成隔水帷幕,确保了开拓巷道安全通过导水构造破碎带,有效地解决了矿山基建期的防治水问题.Tongren mercury mine is a fissure and filling water mine deposit with high level. The crush of faultage and sudden inflow of water will lead to mine flooding when the mine is under construction. To avoid flooding accidents, TSP202 hydrology and geology accident prediction system is utilized. Purdah and slip casting technology is applied to fix up some curtain grouting holes on the working plane after grasping the overall hydrology and geology conditions of the surrounding rock of roadway. Slip casting forms waterproof curtain surrounding the roadway, preventing the faultage from being crushed and flood events from happening during the construction period of mine.
