综合物探及三维解释在采空区探测中的应用
|
摘要
文章针对甘肃省某矿区内的煤矿采空区分布,以瞬变电磁法(TEM)为主,利用高密度电法和可控源音频大地电磁法(CSAMT)对TEM圈定的异常区进行了探测验证,并将TEM处理之后的数据体利用Voxler软件在三维空间内成图。通过纵横剖面及三维空间全方位分析解释,以及多种物探方法互相验证,证明了探测结果的真实性和可靠性,降低了物探解释的多解性,为以后采空区及溶洞的探测提供了新的解释方法。
Aiming at the situation of the coal goaf in certain mine area of Gansu province, the transient electromagnetic method(TEM) is mainly used to determine the abnormal area which is verified through the high density electrical method and the controlled source audio magnetotelluric method(CSAMT). The three-dimensional data body processed by TEM is mapped in 3 D space by using Voxler software. By means of the comprehensive three-dimensional spatial analysis and the mutual verification with various geophysical exploration methods, it is proved that the detection results are authentic and reliable, which reduces the multi-solubility of geophysical exploration and provides a new interpretation method for the exploration of goaf and karst caves in the future.
