摘　　要：矿井工作面回采施工过程中常会遇到小型断层、陷落柱等不良地质构造。构造的存在将破坏煤层连续性,甚至成为潜在的导水通道,若未能对其及时查明将会影响工作面回采安全。单一物探方法受复杂地质条件、施工干扰等因素影响,对规模较小的地质构造判断误差较大,本文以曙光煤矿1230工作面为例,研究使用地震属性成果作为前期指导,对小构造针对性地开展矿井探地雷达及瞬变电磁探测。回采验证结果表明,该地面—井下联合物探方法可查明工作面内构造的展布形态及其含水特征,为工作面的安全回采提供技术保障。Poor geological structures such as small faults and collapse columns are often encountered in the mining construction of mine working face.The existence of the structure will destroy the continuity of the coal seam and even become a potential water channel.If it is not identified in time,it will affect the safety of the working face.The single geophysical exploration method is affected by complex geological conditions,construction interference and other factors,and the judgment error of small-scale geological structure is large.Taking No.1230 face of Shuguang Mine as an example,this paper studied the use of seismic attribute results as the preliminary guidance to carry out mine ground penetrating radar and transient electromagnetic detection for small structures.The mining verification results showed that the surface-underground combined geophysical exploration method could find out the distribution pattern and water content characteristics of the structure in the working face,and provide technical support for the safe mining of the working face.
