摘　　要：随着各地兼并开发的老煤窑、小煤窑比例的增加,煤田开采所面临的地质问题、尤其是采空区越来越复杂,掘进中极易引发突水事故。针对这一问题,笔者阐述了三维地震、高密度电法、可控源电法一体化综合物探解释技术用于解决煤田多层采空复杂区勘探研究方法,实际勘探结果证明,综合物探解释技术能有效地解决煤矿采空复杂区勘查。With the increasing amalgamation of the old mines and small mines, geological engineering problems tend to increase, espe-cially the problems related to coal goal. These geological engineering probleras are likely to result in water inrush during mining. Aimed at solving these problems,the authors describe the achievements obtained from the integrated geophysical interpretation of the 3D seismic method, DC topography and controlled source electromagnet data for detecting the multilayered mined-out complex area. With an exploration example, the practical effects of these technologiesy are also discussed in this paper.
