对矿床进行经济评价时,要涉及矿体的平均品位C_P、矿体的矿石量Q_K和矿体金属储量Q_J三项指标.一般说来,这三项指标是由矿体的边界品位C_B决定的,即C_P、Q_K、Q_J与C_B之间存在着函数关系.本文将建立C_P、Q_K、Q_J与C_B之间的具体函数关系;并以C_B为自变量,把C_P、Q_K、Q_J表示在同一个直角坐标上,做成CCQQ图. 本文引用某金矿床的储量试算资料作为例子.该矿床矿体产在硅化砂岩和硅化砂岩内形状
The economic evaluation of the deposit involves the average grade of the ore body C_P, the ore body ore volume Q_K and the ore body metal reserves Q_J three indicators.In general, these three indicators are determined by the ore body’s boundary grade C_B , That is C_P, Q_K, Q_J and C_B there is a functional relationship between.This paper will establish C_P, Q_K, Q_J and C_B between the specific functional relationship; and C_B as an argument, the C_P, Q_K, Q_J in the same Cartesian coordinates, made of CCQQ map.This article quoted the reserves of a gold deposit trial calculation as an example of the ore deposit in silicified sandstone and silicified sandstone shape
