摘　　要：隐伏地质异常体是煤矿生产中的重要安全隐患之一。为了精准查明李一煤矿工作面的地质异常体,此次研究依据三维地震、瞬变电磁、天然地磁波、测井和钻探等多种探查手段成果,查明了李一煤矿4806工作面地质隐患的类型、空间分布和发育情况,综合解释了其地质成因。研究结果表明,4806工作面异常区为构造作用形成的断层地质异常体,而并非岩溶陷落柱;异常体内具有一定的富水性,且断层沟通了太原组灰岩含水层,因此,必须提前采取治理措施,并再次通过综合方法验证后才能回采。Hidden geological anomalies are one of the important hidden dangers in coal mine production.In order to explore the geological anomalies of the working face,the types and spatial distribution of geological hazards in the 4806 working face based on the results of various exploration methods such as three-dimensional earthquakes,transient electromagnetics,natural geomagnetic waves,logging and drilling were identified.And developmental conditions,its geological causes were comprehensively explained.The results showed that the anomalous area of the 4806 working face was a fault geological anomaly formed by tectonic action,not a karst subsidence column.The anomalous body had a certain water abundance,and the fault communicates with the limestone aquifer of the Taiyuan Formation.Therefore,treatment must be taken in advance.It can only be recovered after passing the comprehensive method verification again.
