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。
Based on the comparison of many geophysical methods, the parallel hydrogeological conditions of coal pillar recovery in Baishan Coal Mine are complex. The water-richness of the hydrological anomaly area of 681 working face is detected by parallel electrical method and verified by other geophysical and drilling methods. Practice shows that the parallel electrical method is sensitive to water-rich areas in complex hydrological areas and has a high accuracy in detecting relatively water-rich areas. The detection results effectively guide the prevention and control of water construction on the working face and ensure the safe mining face.
