Quality criterion for managing operational reliability of mining equipment system: A case-study of Buribai GOK

The analysis of the causes of production process failures at a number of domestic mines has shown that the majority of the causes are due to sudden equipment failures. The development of the production process based on taking into account only the equipment failures that have occurred allows an insufficiently accurate prediction of initiation, growth and, finally, occurrence of a failure event, and disables the effective measures to be implemented improve efficiency of a mine. In this regard, it is necessary to use a risk-oriented approach to reducing the number of failures in a mine’s production process by transferring sudden equipment failures to the predictable category based on identifying and eliminating prerequisites that cause the failure occurrence. This article presents the results of the study into the structure of equipment failures at process stages at Buribai Mining and Processing Plant (Buribai GOK). The study reveals that a significant portion of equipment failures are caused by the unsatisfactory operation of equipment at adjacent process stages. The unsatisfactory operation leads to creation of pick loads applied to equipment at the other process stages. As a result of such equipment failures, employees responsible for its technical condition become hostages of the situation, since they lack authority and resources to influence performance of equipment at adjacent technological stages, which govern the cause of equipment failures in their area of responsibility. Taking into account the identification of equipment failures due to unsatisfactory performance of equipment at the adjacent process stages, a criterion for assessing the risk of failure of the production process is developed, which allows identification of such failures and substantiation of effective solutions for improving the quality of management over operational reliability of a system of process mining equipment.
