摘要
目前，国内众多矿山急需一些投资小、见效快的勘探方法，以解决燃眉之急。将电法勘探中的激发极化法应用于矿山坑道，利用坑道有限的空间区域，开展就矿找矿，是较为理想的选择。实际测量中采用穿、沿脉结合的测量方法，寻找坑道附近的隐伏矿体或评价已知矿体的规模等，为矿山扩大储量服务。近年来，前人在坑道激电的应用方面做了不少工作，也积累了不少好的经验。笔者在吸收前人工作经验的基础上，在陕西某金矿和内蒙某金矿应用坑道激电寻找深部隐伏矿，为矿山解决接替资源问题，取得了良好的效果。同时，指出了开展坑道激电深部找矿时需要注意的几个问题，包括空间的制约、噪声的影响、电磁波的干扰以及矿体分布的全方位等，希望能给以后的工作者起到一定的借鉴意义。
A number of mines in China need an effective and efficient exploration method in a small investment to lift the pressure of resource crisis. Using a limited space, the IP method used underground to carry out prospecting ore is an ideal choice. In practice, it adopts combined crossing and along vein measurement to search for hidden orebodies near a tunnel or to evaluate the known orebodies for expanding reserve. In recent years, predecessors have done a lot of work and accumulated abundant experiences on Tunnel-IP application. Based on the previous work, this study, using Tunnel-IP, tried to prospect deep ores in two gold mines in Shaanxi and Inner mongolia and made contributions for sustainable development for the mines.. In the conclusion, several issues about Tunnel-IP which need to pay more attention to are brought about, including space constraint, noise effect, electromagnetic interference and all-direction distribution of ore etc. , the references would be provided to the future workers.
