Abstract: This article explores the experience of JSC Buribaevsky Mining and Processing Plant in improving ore flow uniformity, which significantly impacts the efficiency of the processing plant and, consequently, the overall performance of the enterprise. It is found that ore flow uniformity is determined by the performance and maintenance of the underground mining equipment. Unsatisfactory performance and maintenance of the underground mining equipment leads to sudden equipment failures and production interruptions, leading to a decrease in ore flow uniformity. An assessment of the performance of the departments responsible for these processes revealed opportunities for improving their performance measurement systems, as well as remuneration systems, to enhance the performance and maintenance of mining equipment. A new bonus system was developed for the department managing mining equipment operations, based on a shift from assessing the fulfillment of a "general monthly mine plan" to daily calculations of individual performance indicators for each mining group. Key changes in the mining equipment maintenance service included improving the mechanics and electrical mechanics' payroll system, as well as enhancing the equipment failure reporting system. Importantly, these changes to improve ore flow consistency were implemented simultaneously in both the operations management and maintenance services. These changes enabled the involvement of mining and maintenance personnel in implementing solutions to improve their performance and a set of organizational measures. This resulted in increased efficiency in the operation and maintenance of mining equipment, ultimately contributing to a more consistent ore flow to the processing plant.
