【摘要】 针对汶南煤矿界外巨空水严重影响矿井安全生产的这一工程难题,通过引进高密度电阻率法对其进行了勘探.基于对高密度电阻率法的基本原理、野外数据采集工作以及数据的整理和分析的研究,可以利用电阻率的变化情况来判断煤层的开采情况,然后对已开采煤层(采空区)部分,通过电阻的大小来判断采空区的含水状况.通过使用该法在汶南煤矿界外巨空水的探测结果来看,高密度电阻率探测法具有准确率高,可视性强,方便快捷的特点,具有一定的工程参考价值.更多还原

【Abstract】 According to the engineering problem that the empty water seriously affected mine safety production in the Wennan coal mine,it was explored by using the high density resistivity method.Based on the study on the basic principle,the job of field data collection and trim and the analysis of these data of the high density resistivity method,the seam mining condition could be judged by using the resistivity changes.And then the water-bearing condition of goaf to the minied coal seam(goaf) was judged according to the size of resistivity.According to the detected result of huge empty water outside of the Wennan coal mine,the high density resistivity method has the advantages of high accuracy rate and strong visibility,and has some reference value for practical engineering.更多还原
