摘要
在新的GB/T 13908-2020固体矿产地质勘查规范总则中,要求对矿体外推一般是按推断资源量勘查工程间距1/2(与2/3)尖推或1/4(与1/3)平推推断资源量.但笔者认为如此估算推断资源量有两点值得探讨:(1)对尖推一般常用楔形和锥形的两种方式进行尖推,故对其资源量的估算也会得出的是两个不同的结果,因此也就无法与平推推断资源量的结果相互一致.(2)在对其尖推体积中的其尖端部位,由于不达开采技术条件中的其最小可采厚度工业指标,因此对其估算推断资源量也存在问题.为合理地估算矿体外推推断资源量,本文通过论证提出了针对性解决上述存在问题的建议.
Abstract
In the general rules of the new GB/T 13908-2020 Code for geological exploration of solid minerals,it is required that the extrapolation of ore bodies is generally based on 1/2(and 2/3)sharp extrapolation or 1/4(and 1/3)flat extrapolation based on the exploration project spacing of inferred resources.However,the author believes that there are two points worth discussing in this estimation of inferred resources:(1)The two ways of sharp infer-ence are generally used to make sharp inference,so the estimation of its resources will also get two different results,so it cannot be consistent with the results of flat inference of resources.(2)Due to the fact that the tip part of the peak thrust volume does not reach the industrial index of the minimum mining thickness in the mining techni-cal conditions,there are also problems in the estimation of inferred resources.In order to reasonably estimate the extrapolated resources of ore body,the paper puts forward some suggestions to solve the above problems.
