地震CT法隐伏矿脉空间定位研究

利用0．5ms采样的高分辨率地震CT方法对宽度不足1m的隐伏矿脉进行了有效的观测和追踪．本研究不只限于地震CT方法常采用的地表一井孔、井间、坑道等观测方式，而是适当地利用矿田地形实现了近似全方位的地震CT野外数据采集，在本研究提出的非均匀介质射线追踪方法下实现了对隐伏含金石英脉的定量观测．

LOCATING SUBSURFACE AURIFEOURS QUARTZ VEIN BY MEANS OF SEISMIC TOMOGRAPHY

If the terrian was put a tational use, a buried lodge of width less than lm could be effectivly observed and truced by making use of the high resolution seismic CT methods. This research makes a break through on the common seismic CT observing ways, such as surfaCe-hole, betWeen holes, pit and so on. It properly takes advantage of the orefield terrian and approximately brings about omnibearing seismic CT field data cellecting. Morever, it also brings about the quantitative observing of the buried gold-bearing quartz veins by using the non-homogeneous media rays tracing methods.
