应用综合物探方法探测煤矿采空区
The Application of Integrated Geophysical Method to the Survey of Goaf of Coal Mines
【摘要】 采煤活动造成的地下采空区会引发地表沉陷等严重的地质灾害,影响人们正常的生产和生活活动。根据煤矿采空区表现出来的地球物理特征,能够利用高密度电阻率法、瞬变电磁法、地震勘探、测氡法等物探方法探测其位置和范围。选择两种或两种以上的方法组合,可以实现优势互补,提高物探的解释精度。
【Abstract】 The underground goaf created by coal mining may cause serious geological hazards such as surface subsidence, interfering normal human activities. A lot of geophysical exploration methods such as high density resistivity method, transient electromagnetic method, seismic exploration and radon measurement can be used for determing the location and the influence scope of goaf. Comprehensive utilization of these methods can increase the interpretation accuracy of geophysical exploration.
