摘　　要：陕北榆横矿区煤层的富水性一直威胁着煤矿的生产安全。为进一步查明巴拉素井田含水层与主要煤层的富水性特征,了解矿井充水水源、充水通道及充水强度,为矿井防治水及矿井设计、建设及生产提供水文地质依据。基于地面物探方法中的瞬变电磁法对高导异常体的富水区及含水构造有较高灵敏度等特点,采用地面瞬变电磁法对该煤田22盘区主要含水层及煤层富水性进行探测。通过对3个主要含水层和两个主要开采煤层的探查,分别划分出相应低阻异常区,并对划分出的高导异常区成因分别进行了综合分析。结果表明,瞬变电磁法对榆横矿区富水性探测具一定优势,可为该煤矿后期生产开展矿井水防治提供技术保障,也可对区域内类似条件矿井提供一定的借鉴意义。The water-rich coal strata in the Yuheng mining area of Shanbei Province have always threatened the safety of coal production.Especially,in order to further find out the water-rich characteristics of aquifer and main coal seam,and understand the water-filled source,water-filled channel and water-filled intensity of mine,it provides hydrogeological basis for mine water control and mine design,construction and production.Based on the characteristics of transient electromagnetic method(TEM)in surface geophysical prospecting,it has high sensitivity to the water-rich area and water-bearing structure of high conductivity anomaly body,in this study,the surface transient electromagnetic method is used to detect the water-rich property of main aquifers and coal seams in 22 blocks of Balasu mine field.Based on the exploration of three main aquifers and two main coal seams,the corresponding low resistivity abnormal zones are divided,and the causes of the high conductivity abnormal zones are analyzed comprehensively,the results show that the TEM method has certain advantages in detecting the water-rich property in Yuheng mining area,and it can provide a technical guarantee for the later production of this mine to carry out the prevention and control of mine water,it can also provide some reference for similar conditions mines in the region.
