On the issue of assessing the reliability of technical devices at mining enterprises

In order to control the current situation, prevent failures and emergencies by taking timely measures to ensure the safety of technical devices it is important to assess their reliability. The presented methodological approach to assessing the reliability of technical devices condition is based on obtaining a single comprehensive indicator that allows determining the degree of reliability of equipment and assess its condition in real time, as well as take into account the criticality of its failure for the main activities of the enterprise. It is proposed to divide the indicators collected by enterprises into three groups, First is identification. The second – operational, allowing to obtain current information and to consider other aspects of the impact not related to systemic impacts. The third one is system, reflecting the ability of the system to perform continuously its functions, taking into account the state of the technical device and the level of impact of its failure on critical areas of the enterprise. It is proposed to use the technical readiness coefficient, the wear index and the criticality index as system indicators of the reliability of technical devices. These indicators should be collected into a single information base, using a unified form for convenience, which allows one to quickly collect and structure information, eliminate its duplication and analyze and evaluate the reliability of technical devices. The use of such an approach will allow, based on the identification of key reliability indicators, to predict the state of reliability of technical devices, and will also help to make organizational and technical decisions aimed at improving reliability, preventing and minimizing the consequences of failures and emergencies.
