Ore quality management in mining planning

Abstract

The problem of ore averaging as a method of product quality management is a complex of specific tasks, the cumulative solution of which allows to carry out quality stabilization. These include: the development of highly effective and reliable express methods for determining the quality indicators of ore; the study of genetic laws of the location of useful components in the subsurface; the choice of the optimal order of mining ore bodies, which ensures the minimum dispersion of the quality indicators of the extracted ore; planning the mining of operating areas; operational management of mining volumes; mixing ores in special warehouses, stacks and bunkers. Ore averaging is a complicated task, requiring the use of methods of mathematical analysis. As one of variants of the decision of such problems the method of computer planning of mining works is offered on the basis of the information on the content of useful components in ore received at a stage of operational exploration of a deposit, and also at sampling in exit excavations of the clearing block.
