统计特征约束矿产储量计算法

A Method of Calculation on Ore Reserves with Statistical Characteristic Constraint

本文从用于矿产储量计算(估算)的已知样本的样本品位、样本体积的概率统计分布特征对矿产储量计算(估算)的结果(矿石量、金属量、平均品位)具有某种制约性或具有某种本质的制约关系这一角度出发,提出了统计特征约束矿产储量计算法,以及这种方法的思想、概念及其这种方法的计算表述式。本方法不仅可以与现今的各种矿产储量计算(估算)方法有一定的联系,而且可以将现今的各种矿产储量计算(估算)方法从一个新的角度,即矿产储量计算结果与产生这种结果的已知样本的统计特征存在着某种制约关系的角度加以拓广及改进。

In this paper, a method of calculation on ore reserves with statistical characteristic constraint, new idea and new cencept of the method, and calculation expression of the method are first presented from the angle that probability statistical distribution characteristic of sample grade and sample volume of given samples in calculation or estimate on ore reserves has constraint or essential restricted relationship to the results(i.e., quantity of ore, quantity of metal, and average grade) of calculation or estimate on ore reserves. the method not only may certainly belongs with methods of calculation or estimation on ore reserves until recently but also can opens up and makes better those from a new angle that the result of calculation on ore resesves exists some restricted relationship with statistical characteristics of given samples producing the result of calculation on ore reserves.
