Modelling of mining performance indicators for the Sadon ore deposits

Relevance. The efficiency of mining operations depends on the level of ore losses and dilution and it can be increased by improving the mining and ore processing methods, therefore research in this area is both timely and relevant. The purpose of this study is to improve the performance indicators of mining of minerals by modelling the technological parameters. The subject of the research are hard rock ore deposits developed by mining companies in various sectors of the national economy. Methods. Systematization and system analysis of the mining performance indicators, economic and mathematical modeling with technology assessment as well as engineering predictions of the prospects to solve the challenge based on the combination of traditional mining systems. Results. The paper presents the results of modelling mining performance indicators using a specific mining operation as an example. A system analysis of mining performance indicators has been performed for metal deposits as well as for performance criteria of the mining companies. Principles for combining traditional mining systems are formulated based on minimization of technologically unconditioned volumes of rocks. A methodology to optimize the options for combining technologies is presented. A correlation mechanism has been established between the quality of mined ores and geodynamic processes. A concept of optimum control is proposed as well as a solid discrete medium model which allows to control the stresses using technological techniques.
