铜录山矿是一座典型的矽卡岩型多金属岩溶矿山,采用露天与地下联合开采,地下水受岩溶与接触带复合控制. 洪水期,临近的小清河河床岩溶反复塌陷、河水沿地下岩溶涌入矿山,长期困扰着井下开采的生产安全. 为了彻底消除矿山水患, 在河床两岸及露采坑边坡布设了3条高密度电阻率法探测剖面,通过计算机将数据经相应畸变点剔除、地形校正、数据平滑等预处理后,最后经过二维反演、处理绘制成视电阻率等值线剖面图,再通过岩、土层电性对比分析出小清河流域岩溶发育特征及地下水主径流通道,同时根据探测成果对河床底部的岩溶进行注浆充填,封堵了河床塌陷区与矿坑之间的主径流通道,达到了较好的堵水效果.

Tonglushan mine is a typical Skarn-type polymetallic Karst mine, which used open-pit and un-dergrounding combined mining method. The groundwater is complexly controlled by contact zone and Karst. Xiaoqinghe river water poured into the pit through the collapse because the river-bed repeatedly collapsed during flood period. Thus the production safety is plagued chronically. To eliminate mine inundation, we em-placed three high density resistivity detecting profiles on the two banks of river and the open-pit slope. After processing data by rejecting distortion point, terrain correct and smoothing, we got the apparent resistivity contour by 2D inversion software. We got the Karst characteristics of Xiaoqinghe area and the main channel of runoff by comparing the electric differences of geological bodies. We filled the Karst fissure under river by grouting according to the detection result, and the main channel of runoff between the river and the pit was plugged, which has satisfactory effects on water plugging rate and reducing cost.
