固体矿产资源储量1999分类修订方案

The modification scheme on China 1999 Classification of Solid Mineral Resources/Reserves

本修订方案坚持1999分类(GB/T17766—1999)的正确方向,侧重弥补其G轴(地质可靠程度)层次混淆之缺陷。明确第一层次分类作总体衡量,以勘查阶段划分,与联合国1997三维分类框架一致;第二层次按块段分级,仍然使用ABCDEF等英文字母,保持我国资源储量管理的精华。删繁就简,E轴2S、2M合而为一。以"精查"代替"勘探"。本修订方案简单明了,与联合国分类框架接轨,便于进行国际对比与交流,同时保留了中国矿产储量管理的特色。解决了1999分类繁杂的"归类编码"问题、同一项目被定为不同可行性研究阶段的问题、分类分级层次混淆大幅度贬低中国储量问题,以及资源储量评审与可行性研究有机衔接问题,可以与现行管理体制相适应,与1999分类平稳过渡。

This modification persists the correct direction of 1999 Classification（GB/T17766—1999）,emphases on to make up for a deficiency of level confusing on the C axis.It conforms the first level classification as the major classes,divided based on exploration stages and keep consistence with UN international framework classification of reserves/resources;the second level distinguished based on blocks,and still use A,B,C,D,E,F categories to remain the best features of past Chinese Classification.To delete the prolixity and keep simple and understandability,merge the 2S and 2M categories on the E axis.For the ＂detailed exploration＂,use the different Chinese word.This modification is simple and understandability,and is correlates easily with UN international framework classification,so is convenient for international exchange and category correlation,and kept the features of original Chinese Classification.It can solve many problems such as complex category coding of 1999 Classification,in which the same item was considered as the results of different feasibility study levels,the class and category mixed with each other,all of them depreciates Chinese mineral reserves and resources classification;it can also solve the problem on the connection between reserves review and feasibility study,fits to the current adminitrative system either,and accomplish the smooth transition from 1999 Classification.
