| 摘 要： | 近年来,隧道超前探测、泄洪洞病害部位探测、矿洞内矿体方位及含水等地下洞体内的探测需求变得越来越迫切,但由于洞内工作面狭小、不是地表的1/2空间、潮湿、金属等低阻体干扰等的特殊工作条件,较难进行有效探测,从而使洞内探测成为一大难题;根据瞬变电磁(TEM)方法的特点,设计了适用于洞内探测的装置,开发了相应的包含数据组合滤波、弱信息增强处理、异常分离等数据预处理方法在内的处理程序,较好地解决了上述问题,并取得了良好的应用效果。

| Abstract: | It has been in urgent need in recent years to carry out pilot detection for tunneling, to detect desease locations in diversion tunnels, to detect ore-or water-bearing bodies in mining works, etc. However, because of special working environment, say limited room, high humidity and strong interferences of conductors, it is very difficult to perform geophysical surveys in such underground caves. Aiming at these problems, a TEM device suitable for working in the caves, along with soft wares including combined filtering and signal enhancing, has been developed. Results of trail surveys have born out the effects of the device. |
