Abstract
Relevance. In the case of shallow deposits, the production capacity of a mine, from the perspective of mining potential, depends on the size of the working horizontal ore area, the mining method employed, the productivity of the extraction unit, the unit area, and their number mined simultaneously. The productivity of a unit is determined by the operational performance of the self-propelled equipment complex used for ore stoping and transportation, which typically consists of a load-haul-dump machine and a dump truck. The selection of the composition of the self-propelled equipment complex is usually based on the practices of leading enterprises under similar conditions or on the basis of a technical and economic comparison of machine productivity depending on haul distance or cost, without taking into account the unit dimensions or evaluating the efficiency of machine utilization over the course of a year. Objectives. The research is aimed at developing and testing a methodology for determining the optimal mine production capacity based on efficiency assessment and selection of the optimal complex composition of self-propelled equipment for ore stoping and transportation depending on the deposit thickness. Methods Applied. Comprehensive research method has been used, including the analysis of estimated performance indicators of self-propelled equipment complexes, economic and mathematical modeling and graphoanalytical method. Results. A methodology for evaluating efficiency and selecting the optimal composition of a self-propelled equipment complex has been developed. The proposed methodology differs in that it takes into account the unit dimensions, the cross-sections of development and haulage workings, the actual load capacity and the operating number of load-haul-dump machines and dump trucks required to ensure annual production volume. Using the proposed methodology, the optimal composition of the self-propelled equipment complex and the annual production capacity of the mine provided by this equipment complex have been determined, depending on the deposit thickness, varying from 10 to 25 m. Conclusions. It has been established that the efficiency of the self-propelled equipment complex depends on the correspondence between machine parameters and the mining-geological and mining-technical conditions of operation.
