Method and system for evaluating mineral resource of mineral concentration area scale

Abstract

The invention discloses a method and a system for evaluating a mineral resource of a mineral concentration area scale. The method comprises the steps of firstly through constructing an ore concentration area ore deposit database, calculating a mineral containing coefficient and establishing a mineral concentration area scale three-dimensional model, wherein the mineral concentration area ore deposit database comprises a stratum mineral-controlling digital model, a rock mineral-controlling digital model and a contact part mineral-controlling digital model and comprises a majority of minerals, thereby breaking an existing application restriction; then obtaining the volume and uncertain coefficient of a three-dimensional geologic body through the mineral concentration area scale three-dimensional model, improving accuracy in acquiring size of the mineral geologic body; and accurately estimating prospective resource amount of the mineral concentration area scale through acquiring a similarity coefficient of each mineral deposit, the obtained mineral containing coefficient, a high-precision volume and an uncertain coefficient. Therefore the method or the system provided by the invention can break the existing application restriction and furthermore improves reliability in prospective mineral resource estimation.

Description

technical field [0001] The invention relates to the field of prospect estimation of resources, in particular to a method and system for estimating mineral resources at the scale of an ore concentration area. Background technique [0002] With the acceleration of my country's industrialization and urbanization process and the increase in resource demand, geological environmental problems are becoming more and more serious. At present, many large and medium-sized minerals in my country have become resource crisis mines due to the depletion of geological reserves. However, many of these mines are due to insufficient investment in geological exploration and unclear resource potential in their deep and peripheral areas. In order to solve the above problems, the resource prospect estimation method is mainly used to predict the mine resource potential. Its resource prospect estimation methods mainly include three-step method, volume method, abundance value method, deposit model me...

AI Technical Summary

Problems solved by technology

Its resource prospect estimation methods mainly include three-step method, volume method, abundance value method, deposit model method, subjective probability method and grade-tonnage model method, but the above methods generally have the following disadvantages; for example, most methods are only suitable for Sedimentary minerals are not suitable for other types of minerals, and have certain limitations in practical application; the spatial distribution of the environment in which ore bodies occur in nature is very complicated. At present, we are only looking for suitable simple polyhedrons to replace the ore-bearing geological bodies in the real world , this process requires a lot of geological knowledge, and then it is calculated from the artificial two-dimensional space, and then pushed down to the three-dimensional space, which is easily affected by human factors, making the volume formula of ore-bearing geological bodies inaccurate and reducing the credibility of resource prospect estimation Spend

That is to say, the use of the above method will lead to low reliability of resource prospect estimation, and has certain limitations in practical application
