矿业权交易中铅锌矿床资源储量验证方法探讨

Discussion on verification method of estimated reserves of the lead-zinc deposit during the transaction of mineral right

在矿业权交易中,资源储量是双方交易的核心标的。如何利用少量验证工程定量判断资源储量的可靠程度,并通过有限的验证工程估算验证后矿床的资源储量,是一个需要探讨的问题。文章从地质统计学角度,提出了用验证工程比较法求可信度并估算资源储量,即用验证前后的平均矿化强弱评价指标因子比率求证验证后资源储量,用平均可信度定量描述被验证工程及资源储量的可靠程度,在实践中取得了较好的效果。

The core subject matter is the estimated resources or reserves in the professional reports for both parties who involved into the transaction of the mineral right.However,it is always a question that how to judge quantificationally the reliability level of estimated resources or reserves in the exploration report by conducting less verification drilling work,and estimate the deposit resources or reserves after conducting the verification drilling work.In this paper,the comparison method of verification engineering was put forward to evaluate its reliability level of the estimated resources or reserves,and further calculate resources or reserves after verification engineering.The principle is to use the ratio of index factors of average mineralized intensity before and after verification engineering to obtain resources or reserves after verification engineering,and the average reliability level is quantificationally used to represent the reliability of verified exploration work and estimated resources or reserves,finally the sounding application effect has been achieved in the case study of one lead-zinc deposit.
