摘要
本文概述了国内外矿产勘查阶段划分的情况。论证了分阶段进行矿产勘查,可以把勘查费用压缩到工作所必需的程度上,并把那些在工作过程中不应该出现的消耗社会劳动的地质风险和经济风险控制下来。为了提高矿产勘查效果,普查阶段要注意选区,保证原始地质资料质量,有效运用综合技术方法找矿,从实际需要出发研究矿床,并及时对普查的矿床作出选冶试验和技术经济评价。
The present paper has outlined division of exploration stages for mineral deposits at home and abroad, and has proved that the exploration for mineral deposits stage by stage can cut back exploration expenditure and get geological and economic risks under control. In stage of reconnaissance survey, in order to increase effectiveness of exploration for min-eral deposits, care must be taken to select target, to guarantee quality of initial data, to utililze comprehensive method, to research deposits from actual conditions and to make separation and metallurgical tests and to evaluate technical and economic indexes for the explorated deposits.
