阳泉矿区煤田采空区综合地球物理探测模式应用

为支撑采煤沉陷区地质环境调查与矿山环境恢复治理工作,对山西阳泉矿区典型采煤沉陷区开展综合地球物理勘探技术方法研究与应用示范。通过重力勘探、浅层地震法和瞬变电磁法开展煤田采空区地球物理方法对比应用研究,总结出采用以上3种物探方法相结合的勘查煤田采空区的有效探测模式。探测结果表明,综合地球物理勘查结合地面地质调查能够识别采空区边界和深度等属性信息,为采空区三维地质建模提供数据依据。

Application of comprehensive geophysical exploration model of coal mining goaf in Yangquan mining area

In order to support the geological environment investigation and mine environment restoration and management in coal mining goaf area,the research and application demonstration of comprehensive geophysical exploration technology method were carried out in the typical coal mining goaf area of Yangquan mining area,Shanxi Province.Through gravity exploration,shallow seismic method and transient electromagnetic method,the comparative application of geophysical methods in the coal mining goaf is studied,and the specific model of goaf exploration of coal field by combining the above three geophysical methods is summarized.The exploration results show that the comprehensive geophysical exploration combined with the ground geological survey can identify the attribute information such as the boundary and depth of the goaf,and provide the data basis for the 3D geological modeling of the goaf.
