摘要
地球物理勘探方法以快速、无损的特点被广泛使用,但是采用单一的物探方法,会受到探测结果多解性的约束,检测结果可能不合理。通过2次物探工作圈定疑似采空区,并对疑似采空区进行钻探验证,第1次圈定的疑似采空区经钻探验证并非采空区,第2次圈定的疑似区经钻探验证确认为采空区。介绍了2次物探工作组合方法和工作参数,在第1次物探误判后开展分析和研究又进行第2次物探,最终探查到采空区,为实施采空区物理探查工作参数的选择和异常解释提供分析依据。
Geophysical prospecting methods are widely used because of their rapidity and non-destructiveness, but using a single geophysical prospecting method will be constrained by the multi-solution of the detection results, and the detection results may be unreasonable.Through two times geophysical prospecting work, the suspected goaf was delineated, and the suspected goaf was verified by drilling.The suspected goaf delineated in the first time was verified by drilling to be not a goaf, and the suspected goaf delineated in the second time was confirmed by drilling verification as goaf.This paper introduces the combination method and working parameters of the two geophysical prospecting work, carries out analysis and research after the misjudgment of the first time geophysical prospecting, and carries out the second time geophysical prospecting, finally detects the goaf.And provide analysis basis for the selection of working parameters and abnormal interpretation of physical exploration in goaf.
