立体探测技术在探测陷落柱中的应用

Application of Three-dimensional Detection Technology in Detecting Subsided Columns

从地震槽波勘探和瞬变电磁法两方面对立体探测技术在探测陷落柱中的应用进行了探讨。利用地震槽波勘探对陷落柱的基本形态进行了探测,使用瞬变电磁法对槽波异常区进行了富水性探测。最后针对物探异常区利用最少的钻孔进行了验证,更好地确定了陷落柱的边界及富水性,为巷道掘进提供有力的地质保障。

This paper discussed the application of threedimensional detection technology in the detection of collapsed columns from the aspects of seismic trough wave exploration and transient electromagnetic method.The basic form of collapse columns was detected by seismic trough wave exploration,and the abnormal area of trough wave was detected by transient electromagnetic method.Finally,the least boreholes were used in geophysical anomaly zones to confirm the boundary and waterrich property of collapse columns,which can provide strong geological guarantee for tunnel excavation.
