矿井水一直都是杨庄煤矿采掘过程中的主要威胁,为了查明III51行人下山底板水的赋存状况,采用直流电法对底板进行了探测。介绍了测试方案、测点布置、探测仪器和探测关键技术措施等,并对探测的原始资料进行了评述,通过软件解释,得到了底板视电阻率相对低阻区。结果显示,该处有3处相对低阻区,其中第2低阻区赋水的可能性最大。通过打钻验证,该区域出水量达130m3/min。实践证明,直流电法在煤矿采区底板中探测水非常有效。
Mine water has always been the main threat in Yangzhuang coal mining process. In order to find out the occurrence of the III51 pedestrian water coming down from the floor, the floorboard was detected by DC method. The paper introduces the test plan, the layout of measuring points, the detecting instruments and the key technical measures of exploration, and reviews the original data of the exploration. By software interpretation, the apparent resistivity of the floor is relatively low resistance area. The results showed that there are three relatively low resistance areas, of which the second lowest resistance zone water is most likely. By drilling verification, the water output of the region up to 130m3 / min. Practice has proved that the DC method to detect water in the coal mining floor is very effective.
