摘　　要：大部分煤矿在未揭露和半揭露的煤系地层中勘探开发,导致大量未揭露的含煤地层被掩盖。与昂贵的钻探作业相比,地球物理方法可以更高效、更经济地发现隐伏含煤地层等深部目标。通过综合地球物理勘探方法探测寺河矿区地区的含煤地层,使用大尺度大地电磁(MT)描述地质构造及其剖面,利用航磁测量圈定寺河矿区含煤远景构造单元向斜的空间展布特征。通过可控源音频大地电磁法(CSAMT)和大地电磁法(MT)的局部勘探,揭示了含煤目标可供钻探,钻探结果验证了综合地球物理方法所识别的目标。实例研究表明,多学科地球物理策略能够为深部煤层资源勘探提供可靠的结果和可信的数据解释。Most coal mines are explored and developed in unexposed and semi-exposed coal measure strata,resulting in a large number of unexposed coal-bearing strata being covered.Compared with expensive drilling operations,geophysical methods can be more efficient and economical to discover deep targets such as hidden coal-bearing strata.This paper explores the coalbearing strata in the Sihe mining area by comprehensive geophysical exploration method,and uses large-scale magnetotelluric(MT)to describe the geological structure and its profile.The spatial distribution characteristics of the coal-bearing prospective tectonic unit syncline in the Sihe mining area are delineated by aeromagnetic measurement.Through local exploration by controlled source audio magnetotelluric method(CSAMT)and magnetotelluric(MT),it is revealed that the coal-bearing target is available for drilling,and the drilling results verify the target identified by the comprehensive geophysical method.The case study shows that the multidisciplinary geophysical strategy can provide reliable results and reliable data interpretation for the exploration of deep coal seam resources.
