Abstract

To improve the efficiency of the mining industry, it is necessary to coordinate all production processes, which allows reducing unproductive downtime of mining and transport equipment, increasing their productivity, and reducing the cost of operations at all stages of the production cycle. To achieve this result, the article uses a systematic approach to consider the features of planning the work of all departments of the coal mine, starting with drilling and blasting operations on the sites and ending with the shipment of finished products to consumers. Based on the example of JSC “Chernigovets” in the Kemerovo region, the article considers a two-level model for planning the work of all divisions of the enterprise for a month, taking into account the dynamics of resource use of production and transport sections. Taking into account the uneven performance of production operations and the wide variety of mining equipment used at the stages of preparation, excavation, excavation, transportation, processing and shipment of finished products to external rail transport, it is possible to use a hierarchical two-level system with aggregation of processes at the first level and their detail at the second level. Using the dynamic programming method allowed us to solve the problem of planning the activities of all divisions of the enterprise at the first level and identify the boundaries of changes in the planned indicators at the second level, which do not worsen the results achieved at the first level. The proposed method of planning the operation of the mine will allow you to quickly track the achieved indicators, compare them with the planned ones and, if necessary, adjust the work of the enterprise’s divisions in real time to achieve the best performance indicators of the coal mine as a whole.
