勘查活跃度指标在区域矿产勘查进展评价中的应用:以整装勘查区为例

Application of exploration activity index in the evaluation of regional mineral exploration progress:a case study of the equipped exploration districts

针对勘查投资额和勘查投入实物工作量等统计指标在区域勘查进展评估工作中的局限性(如统计口径不一导致分析结论差异、无法体现区域背景条件差异等),本文提出了单个探矿权勘查活跃度指标、适用于不同区域间横向对比的静态勘查活跃度指标和适用于对比同一区域不同时期勘查进展的累计勘查活跃度指标,并详细推导了各指标的计算方法。通过对全国整装勘查工作进展情况进行综合分析,本文对8种不同类型的整装勘查区进行了初步总结并提出了与之对应的SIEA-OR_(PA)演化曲线。应用结果表明勘查活跃度指标的计算方法具有可操作性,数据源时效性高,分析结果能够客观反映真实情况。

Aiming at the limitations of exploration investment and exploration workload which being used in the evaluation of regional exploration progress, such as the different analysis conclusion caused by statistical caliber and the limitation of reflecting regional difference background conditions, this paper presents a group of calculation method of the exploration activity index. In addition to the calculation method of the exploration activity index being used in the single exploration right, this paper also presents the calculation method of the static index of exploration activity in which is used lateral comparison between different exploration areas. Furthermore,the third one is the calculation method of the cumulative index of exploration activity in which is used longitudinal comparison of the same area. Based on the comprehensive analysis, this paper preliminarily summarizes 8 different types of areas and presents the SIEA -ORpA curve. The results show that the calculation method is operable; the data source is timely,and the results can reflect the real situation objectively.
