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.
