摘要
在现行固体矿产资源量估算规程(DZ/T 0338.2-2020)第2部分几何法中,其对平行断面块段矿体体积参数的计算采用的是传统的模拟断面形状选择体积计算公式的方法;该方法存在的问题是选择计算体积公式的数理依据不足,从而会影响到其对估算资源量成果的客观性.在文中的实例计算中,采用传统方法的计算结果其相对误差达到了7.22%.本研究探讨提出了对平行断面法客观计算矿体体积参数的新方法,可为其估算资源量提供客观的体积参数值成果.
Abstract
In the latest DZ/T 0338.2-2020 Regulation of Mineral Resources Estimation-Part 2:The Geometric Methods,the parallel section method for estimating solid mineral resources is based on the traditional method of simulating the shape of the ore body to calculate the volume parameters.The problem is that the mathematical basis for the method to choose the calculation volume formula is insufficient,which will affect the objectivity of its estimated resource results.In the example calculation in this paper,the relative error of the calculation results using its traditional method reaches 7.22% .In this paper,a new method for calculating the volume parameters of ore body by parallel section method is proposed,which can provide objective volume parameter results for its resource estimation.
