摘要
以矿井CT透射探地雷达探测技术为基础,基于射线追踪理论和ART算法原理,对建立的矿井隐伏构造灾害源数值模型开展模拟探测及反演成像研究,并将此方法应用于实测数据的成像处理。结果表明,此方法能够有效确定异常构造的位置及其尺寸大小,对井下隐伏构造灾害源探测起到了一定推动作用。
Based on CT transmission detection technology of GPR, according to the theory of ray tracing and the principle of ART algorithm to achieve the simulation detection and inversion imaging of the hidden disaster in the numerical model. And using this method to image measured data. The results indicated that travel time tomography by using ART algorithm can effectively identify the location and size of the abnormal structure, which promotes the exploration of hidden structure disaster sources.
