| 中文摘要: |
| 探矿工程是一个逐步缩小工作范围、由浅入深、由表及里、逐渐加密的取样工程。地质勘查是分阶段、有层次进行的,按工作面积由大到小分为5个层次。文章探讨了每个工作层次的工作平台、主要工作内容、野外工作量和预期目标。根据投资经验统计,一个中小型矿床的勘查从选区申请立项到详查结束,用于纯地质勘查上的费用大体需要1330万元(选区—预查阶段130万,普查—详查阶段1200万元)。认为项目建设与找矿前景评价应抓住3个关键:建立专家群体(快速选区)、建立和完善研判准则和流程(快速研判)、建立精干队伍野外调研(快速评价)。建议组建3人快速勘查组半年完成野外预查:2个月完成地质、化探调查,2个月完成靶区验证。 |

| Mineral exploration is accurally an sampling engineering through focussing on target,from surface work to undergrond work,densifying sampling space from stream sediment→soil→rock chip.It is in sequence carried out according to sequential stages.Based on the work area,it is divided into five levels.This paper deals with work platform of each level,content,fieldwork and objectives.Based on the statistics of precious and base matel mineral exploration cost,the investment on small-middle ore deposit is estimated.The whole geological exploration from targeting stage to detailed exploration completion of a small to middle deposit may cost 13.30 million RMB,including 0.3 million RMB at tageting stage,1 million RMB at preliminary exploration stage,4 million RMB at general exploration stage and 8 million RMB at detailed exploration.In targeting and work area selection stage,we should pay attention to three keys,specialist group for quickly targeting,establishing due diligence principle and schedule and geological team for speedy field geological survey.Field geological group of 3 geologists can finish preliminary geological survey within half year,including geological and geochemical work within 2 months and engineering testing within 2 months.If doing so,we can spend 1.3 million RMB finishing targeting and preliminray exploratin.Accordingly,we can spend 12 million finishing general exploration and detailed exploration within 4-5years. |
