阳泉煤业集团五矿8421工作面存在局部带压区,必须查清带压区隐伏灾害地质构造及其含水情况,为工作面安全回采提供保障.通过分析不同物探方法的特点和适用条件,采用无线电波透视法、矿井瞬变电磁法、并行直流电法3种物探方法,对该局部带压工作面进行了综合探测.多种地球物理探测方法相互印证和补充,并结合地质、水文地质条件分析,最终划分出3个底板相对富水区.经采掘验证,物探结果与实际情况相符.%The local pressure zone exists in 8421 working face in No. 5 Mine of Yangquan Coal Industry Group, it is necessary to find out the hidden geological structure and its water content in the pressure zone so as to provide the guarantee for the safe mining of the working face. Based on the analysis of the characteristics and applicable conditions of different geophysical prospecting methods, three kinds of geophysical prospecting methods were selected, including the radio wave penetration method, the mine transient electromagnetic method and the parallel direct current method, with these methods, comprehensive detection was carried out on the local pressure of this working face. Several geophysical exploration prospecting methods were verified and complemented each other, and combined with the analysis of the geological and hydrogeological conditions, three relatively water-rich areas were finally divided. The actual mining verification showed that the geophysical prospecting results agreed with the actual situation.
