Volume estimation method for mineral resource set

Abstract

The invention relates to a volume estimation method for a mineral resource set, and solves the problem that a large error exists between the calculated volume and the actual volume in the volume estimation process of a traditional ore body (block section). According to the method, three-dimensional mining software is utilized; a three-dimensional spatial form of the ore body is simulated in a computer; the volume of an ore body (block section) is read from a computer, the average grade of a single ore body (block section) is calculated by using the computer, the resource / reserve of the singleore body (block section) is calculated by using the product of the volume and the average grade and the ore specific gravity, and the resource / reserve of each ore body (block section) is summarized to obtain the resource / reserve value of the whole ore deposit. According to the method, the problem that errors are generated in the links of projection area measurement, ore body (block section) truethickness calculation and the like is solved, the volume of the ore body (block section) is measured more truly and more accurately, and the resource / reserve estimation precision is greatly improved.

Description

technical field [0001] The invention relates to a method for calculating the volume of mineral resources, in particular to a method for estimating the aggregate volume of mineral resources. Background technique [0002] The purpose of geological exploration is to discover and ascertain the quantity and quality of mineral resources, and how to determine the quantity of discovered mineral resources requires the use of mineral resource estimation methods. At present, the most widely used solid mineral resource estimation method in China is the geological block method. Its rationale for estimating mineral resources / reserves is: [0003] First estimate the volume of the ore body (block), then estimate the average grade of the ore body (block), obtain the specific gravity of various ores through analysis and testing, multiply the volume of the ore body (block) by the specific gravity of the ore, and then multiply The resource / reserve of the ore body (block) is obtained by the ave...

AI Technical Summary

Problems solved by technology

[0042] In order to solve the above-mentioned orebody (block segment) problems such as the large difference between the calculated orebody volume and the actual orebody volume in the process of volume estimation, we use 3D mining software to simulate the 3D spatial shape of the orebody in the computer , directly read the volume of the ore body (block) from the computer, and then use the computer to calculate the average grade of a single ore body (block), and finally use the product of the two and the ore specific gravity to calculate a single ore body (block) resources / reserves, and then summarize the resources / reserves of each ore body (block) to obtain the resource / reserves value of the entire ore deposit
