高承压隐伏导水陷落柱的超前探控与综合识别

Advanced Detection and Control and Integrated Recognition of High Confined Hidden Water Flowing Subsided Column

为实现隐伏陷落柱的预判与精确探查,确定了"地质预判、水质预警、物探定位、钻探控制"的综合探查措施:地质预判即通过水文地质条件和历史陷落柱致灾条件分析,总结出矿区陷落柱发育规律;水质预警即通过对出水点水量、水质、水温、水压的监测分析,确定水源;物探定位即通过"地面-井下"综合物探探查圈定了异常区域;钻探控制即采用定向钻探技术,准确控制陷落柱的空间形态及边界。通过上述综合方案的实施,实现了任楼煤矿Ⅱ51轨道大巷隐伏导水陷落柱的预判与超前精确探查。

To achieve the pre- estimating and accurate exploration of hidden subsided column,we define integrated detection program including geological pre- estimating,water quality early warning,geophysical prospecting location,and drilling control. Geological pre- estimating is the summary of subside column development laws in the area by analyzing hydrogeological conditions and historical column accidents; water quality early warning is to identify the water source by monitoring and analyzing water quantity,water quality,water temperature and water pressure; geophysical prospecting location means to delineate the abnormal areas by ＂ ground- underground＂ integrated geophysical exploration technology; drilling control is to control the spacial form and boundary accurately by directional drilling technology. By means of the comprehensive program,we successfully achieve the pre- estimating and advanced accurated exploration of hidden water flowing subsided column inⅡ51main track tunnel in Renlou Mine.
