Dump Truck Operational Efficiency: A Case Study of the Don Mining and Processing Plant

Abstract

The paper considers the issues of the urgent problem of increasing the efficiency of the organization and planning of the maintenance system of mining dump trucks. The methods of analysis and synthesis of a priori information and statistical data of the enterprise show the need to improve the existing system for ensuring reliable operation of the dump truck fleet. Quantitative indicators are given that characterize the operational reliability of the park as the number of failures of the park as a whole, the main components and assemblies and the coefficient of technical readiness (CTR) of the park, analytical dependencies are obtained that approximate the dynamics of these indicators, depending on the duration of the studied service life. The obtained functional dependencies differ by type, with a significant discrepancy between planned and actual indicators, which in production conditions are eliminated by unscheduled operational measures of technical impact that reduce the overall efficiency of the maintenance and repair system of the fleet. The necessity of increasing the efficiency of the operating system at the stage of planning and organization of maintenance and repair is substantiated.
