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.
Highlights
Applying a systematic approach to the consideration of all production processes of a mining enterprise allows you to link all these processes with each other, identify their mutual influence, and determine the order of interaction of performers to achieve the overall goal of the section
At the stages of mining and moving overburden rocks to dumps, powerful excavatorautomobile complexes operate, the activities of which are subject to many random factors that lead to rapid correction of the processes at these stages [5, 6, 7]
We introduce the following notations: xi — the scope of work for the month on the process i; ci —
Summary
Applying a systematic approach to the consideration of all production processes of a mining enterprise allows you to link all these processes with each other, identify their mutual influence, and determine the order of interaction of performers to achieve the overall goal of the section. The intensity of coal removal from warehouses affects the speed of work on overburden sites (block 2), which, in turn, depends on the timeliness of drilling and blasting operations (block 1). 8. When determining the volume of excavation and loading operations on each horizon, the maximum possible volume of traffic that can be performed by the quarry transport for the planned period should be taken into account. Plan of blasting determines the location and size abusively blocks on every horizon, prepared by the ledges as the result of the hole drilling, the volume of rock mass, the volume of each drilling rig. The volume of rock mass prepared for drilling on the horizon by drilling rigs fixed to the ledge is determined by the productivity of the blasted rock and the desired operation duration of each machine. Search for contours of drilling sites is performed within the specified borders
