摘要
一直以来,利用地球物理方法对多层煤矿采空区的勘查都是比较棘手的问题,由于采空区的多层分布导致更加复杂的地下介质结构,地面及岩层形变也造成了介质层无规律的变化,如裂缝、垮塌、充(填)水等现象,这些都给利用介质差异为工作前提的地球物理勘探带来了很大的技术难度。笔者借助工作实例,来对采用综合物探方法对多层采空区勘查的异常特征与效果进行对比分析,从中获得了一些认识,用于实际勘察工作,效果较好。
The application of geophysical exploration method to the detection of multi-layer goaf has long been a difficult problem. The multi-layer distribution of the goaf leads to very complex underground media structure, and surface and rock deformation also result in such irregular changes of the media layer as cracks, collapses and water filling. All these phenomena cause great technological difficul- ties for the geophysical exploration based on differences in media. With practical examples, the author made a comparative analysis of the utilization of geophysical exploration to detect anomaly characteristics of the multi - layer goal and got some understanding, which was then used in practical exploration work, with satisfactory results obtained.
