Abstract

This article evaluates the current methods for monitoring the technical condition of imported self-propelled loading and delivery equipment, which is operated in real conditions of the mining industry. Comparative assessment of the performance of foreign self-propelled equipment should be evaluated by the indicator of Overall Equipment Effectiveness (OEE), which is evaluated depending on the availability, efficiency and quality of work of the LHD.
The results of experimental and theoretical studies of the parameters of the interaction of the transport-technological system "self-propelled machine - mining environment" and bench tests of LHD parts allowed to state that the vast majority of downtime of self-propelled equipment due to equipment failures can be prevented by improving its system of maintenance and diagnosis. The components of the indicator of the overall effectiveness of self-propelled equipment are determined.
Numerous failures of systems and parts are primarily due to the absence of monitoring schemes at mining enterprises that would allow operational control of the condition of self-propelled imported equipment. In this regard, it is necessary to obtain a database of the causes of failures of systems and parts, which can be considered as the basis for the development of methodological guidelines for the control and testing of the technical conditions of the LHD in real mining conditions.
Based on the automated collection and processing of information about the technical condition of LHD and expert assessment of the resource indicators of units and parts according to the frequency of their failure, it has been established that currently diagnosing the technical condition of foreign-made self-propelled mining transport equipment is a complex integrated task requiring the development of relevant modern methods and measuring equipment with additional software.
