摘要
为查明建设场地内采空区范围及埋深,为工程建设提供基础地质保障,采用瞬变电磁法和高密度电法相结合进行探测。综合物探圈定了煤矿采空区的范围、埋深和面积。结果表明,煤层采空区主要集中在南区,北部地块未发现煤矿采空区,物探成果与实际采空情况吻合较好。
In order to find out the scope and buried depth of the goaf in the construction site and provide basic geological guarantee for the project construction,the combination of transient electromagnetic method and highdensity electrical method is used for detection.The scope,buried depth and area of the goaf of the coal mine are delineated by comprehensive geophysical prospecting.The results show that the goaf of coal seams is mainly concentrated in the south area,and the goaf of coal mine is not found in the north block.The geophysical prospecting results are in good agreement with the actual goaf situation.
