对333、334资源量估算的讨论——以湖南白腊水锡矿床为例

A Discussion on Mineral Resource Estimates of Categories 333 and 334——a Case Study of Bailashui Tin Deposit in Hunan

《固体矿产资源储量分类》及《固体矿产地质勘查规范总则》对334资源量只有原则性的定义,对333、334资源量估算的工业指标及矿体圈定原则没有具体规定,现行规范中对预测资源量的圈定要求过高,同时也没有高于边界品位而低于最低工业品位资源量的编码,致使在资源量估算中不统一。文章试图以白腊水矿区锡矿资源量估算为例,就333、334资源量的估算进行讨论,建议将334分为3341和3342两类,并对333和334的控制程度、圈定原则、资源量编码、工业指标及资源储量比例等有关问题提出建议。

There are general definitions of category 334 resources in＂ Classification for of Solid Fuels and Mineral Commodities ＂ and＂ General Repuirements for Solid Minerals Exploration＂ promulgated by the Chinese authorities, however, industry parameters and orebody delineation rules to categories 333 and 334 resources estimates are not defined specifically, the rules to reconnaissance resources （ category 334） estimate set up in active＂ General Requirements＂ require a higher level of confidence, and there is not resources category between the cut - off grade and minimum mining grade, all these factors lead to the difficufities in appropriate resources estimates. This article attempts to undertake the resources estimates by using the data collected from the Bailashui tin ore district as an example, the categories 333 and 334 resources estimates are discussed. It is proposed that the category 334 could be divided into 3341 and 3342 , and for the categories 333 and 334 resources estimates, the level of confidence, orebody delineation rules, the resources code, the industry parameters and proportion of resources and reserves etc. are discussed.
