勘探阶段的主要任务,是根据矿山开采的实际需要查明地下资源的数量、质量、矿体的三度空间形态和开采技术条件,为拟定矿山建设方案和初步设计提供地质依据.怎样才能更好地完成这个任务呢?在第一个五年计划期间,某些矿区曾采用“类型-网度-ABC”这样一套办法进行勘探.大跃进中和1964年设计革命化以 The main task of the exploration phase is to find out the quantity and quality of underground resources, the three dimensional shape of the ore body and the technical conditions of exploitation according to the actual needs of the mining, and provide the geological basis for formulating the mine construction plan and preliminary design. In the first five-year plan, some mines were surveyed using a set of methods such as “type-net-abc.” In the Great Leap Forward and in 1964, the design revolution
