一九八六年五月,地矿部以张宏仁总工程师为首的赴苏考察组,了解到苏联用地球化学方法寻找隐伏深部矿的一些情况,现简要介绍如下。随着有待查明的露在地表或隐伏浅部的矿床愈来愈少,势必转入寻找隐伏深部矿(深部的概念有两种说法:一种是埋深大于500米即称深部;另一种分为埋深500—1000米及大于1000米,前者算中深部,后者算深 In May 1986, the Ministry of Geology and Mineral Resources, headed by Chief Engineer Zhang Hongren, visited the Soviet inspection team and learned some of the Soviet cases of using geochemical methods to find hidden deep mines. The brief introduction is as follows. As the number of deposits to be ascertained on the surface or in the shallow depths is less and less, it is bound to shift to finding hidden deep mines (there are two versions of the concept of deepness: one is deeper than 500 m, deep; the other Seed is divided into the depth of 500-1000 meters and more than 1000 meters, the former considered in the deep, the latter considered deep
