中国固体矿产储量/资源新的分类标准和联合国储量/资源分类框架

NEW CHINESE CLASSIFICATION OF MINERAL RESOURCES/RESERVES AND UNFC (as it is seen from Russia)

文章论述和对比了中国新的固体矿产储量 资源分类标准和联合国储量 资源分类框架、矿山和冶金研究所协会成员国分类标准以及俄罗斯分类标准的共同点和差别及其兼容性。作者认为 ,中国新的分类标准体系符合联合国储量 资源分类框架和三维结构、各类标准的主要定义和数码 ,认为联合国分类框架中按“G”轴划分储量的方法是错误的。中国专家使用的标准不是地质评价的阶段 ,而是用不同储量等级 (确定资源 ,推定资源和推测资源 )反映的地质可靠程度本身。作者提出的对联合国分类框架的修正方案以及俄罗斯新的分类标准基本上是以中国的分类方法为蓝本的。作者想借此敦促国际间的合作 ,以使各主要采矿大国的分类标准趋向一致 ,使之既适用于编制矿产储量 资源报告 ,又适用于编制经济发展规划 ,通过共同努力来完善联合国储量 资源分类框架 ,并使其能在不同的矿种和不同类型地质的矿床中试行。作者提议创建一个中俄统一的工业储量 资源分类标准体系 ,完善有关标准的术语和定义 ,并共同努力对联合国储量分类框架予以改进。

Discussed in the paper is the new Chinese classification for resources/reserves of solid fuels and mineral commodities compared to the UNFC, CMMI and Russian classification as to the main features in common and differences on which their compatibility may depend. The new Chinese system has accommodated the 3-dimensional structure of the UNFC, its main definitions and codes for individual categories but it has not reasonably applied its erroneous approach to categorization of reserves/resources along axis 'G'. The criterion applied by Chinese experts is not a stage of geological assessment but the degree of geological assurance per se reflected in the names of categories (measured, indicated, inferred). Corrections to UNFC and a new Russian version of classification are proposed based largely on the Chinese approach. The author's position is in favor of furthering international efforts in drawing nearer the classification systems of leading mining countries used for both public reporting of mineral resources/reserves and strategic planning, refining the UNFC and its testing on examples of different mineral commodities and geological deposit types. Advocated is the idea of developing a single Chinese-Russian system of industry reserves/resources classification, perfection of terminology and definitions standards, and joint actions directed to the improvement of UNFC.
