并行电法在矿井复杂水文区域防治水探查工作中的应用

The Application of the Parallel Electrical Method to the Water Prevention Exploration in Complex Hydrological Mine Areas

百善煤矿回收煤柱局部水文地质条件复杂,在比较多种物探方法的基础上,使用并行电法对681工作面水文异常区域的富水性进行探测,并使用其它物探和钻探进行验证。实践表明,并行电法对复杂水文区域的富水区域反映灵敏,对相对富水区的探测准确率高。探测结果有效地指导了工作面下一步的防治水施工,确保了工作面安全回采。

The local hydrogeological conditions of Beishan coal mine are complex. Compa- ring a variety of geophysical methods, the parallel electrical method is used to detect the rich water in 681 working face of the hydrological abnormal area, and the other geophysical method and drilling method are used to verify the forecasting result. The test shows that the parallel electrical method has the sensitivity reaction to the water--rich region of the complex hydrological region. And it has high accurate detection for the relative water--rich area. The detection results are effectively guided to the next step of the prevention and con- trol of water construction.
