为了全面落实国务院关于加强地质工作的决定(国发(2006)4号)和温家宝总理关于整顿矿业秩序的指示精神,从源头上缓解我国目前经济社会发展的资源瓶颈约束,实现矿业秩序的根本好转,国土资源部决定组织启动“全国矿产资源利用现状调查”专项,全面开展矿产资源领域的国情调查。储量核查工作遇到的储量计算的方法可分为几何图形法、地质统计学方法和SD法。本次储量核查工作中有大量运用SD法进行资源储量估算的矿区,在实际工作过程中为了满足核查工作技术要求,我们将每一储量计算台阶假想为一个或若干个独立的“虚拟矿体”(储量估算单元)。通过这种方法可以方便对原块段块段的分割对照以及矿体属性挂接,又可以清晰的划分各个储量级别的块段分布情况,既简化了操作又便于数据的录入与提取。
In order to comprehensively implement the State Council’s decision on strengthening geological work (Guo Fa (2006) No. 4) and Premier Wen Jiabao’s directive on rectifying the order in the mining industry, it is necessary to ease the bottleneck of resources in our country’s current economic and social development from the source to achieve a fundamental improvement in the mining order , The Ministry of Land and Resources decided to organize the launch of the “National Survey of Mineral Resources Utilization Status” special and comprehensive conduct of national mineral resources survey. Reserves verification methods encountered in reserves verification can be divided into geometric methods, geostatistical methods and SD methods. There are a large number of mining areas that use the SD method to estimate the reserves of resources in the verification of reserves. In order to meet the technical requirements of verification work in the actual work process, we assume each reserve calculation step as one or several independent virtual ore bodies "(Reserve estimation unit). By this method, it is convenient for the section control of the original block section and the articulation of the orebody property, and the division of the block sections of each reserve level can be clearly divided, which simplifies the operation and facilitates the data entry and extraction.
