| Summary: | The relevance of the work is determined by the intensive deterioration of the ore-raw material base of the mining enterprises of Norilsk, which leads to a deterioration in the quality of the extracted ores. During the transition from the development of rich ores to disseminated ores, fluctuations in the quality of ore create significant difficulties in ore processing, worsening the technological indicators of enrichment and reducing the economic efficiency of the entire mining and metallurgical complex of the PJSC MMC Norilsk Nickel. The article is devoted to solving the problem of stabilizing the material com- position of ores during underground mining for a set of modernization of the mine information system, which ensures a decrease in quality variability. In the work, the conditions and ways to improve the stability of the composition of poor cop- per-nickel ores were studied using the example of the Norilsk-1 deposit in the conditions of the Zapolyarny mine. The most significant way to solve the problem of stabilizing the quality of mined ores is organizational and technological, performed in the process of mining and at the stage of preparing ore-mineral raw materials for enrichment. The idea of the work is that an underground mine is considered as a production system that can reduce the level of variability of the content of useful components in the ex- tracted ore in the high-amplitude part of the spectrum during mining operations. In the work, the stabilization process is considered as a complex of planning and organizational methods aimed at achieving the average absolute value of the quality of the ore mass. The information-operational mining system for stabilizing the quality of ores during mining includes planning, (decade-daily schedule (DDS) i.e., a short-term planning tool for the decade-shift period Micromine MineSched AutoCAD) organization and management of mining, with using radiometric and electronic technical means. The goals and objectives underlying the organizational component are the timely preparation of mining plans, control and coordination of the main areas of the mines production aimed at improving the efficiency of mining. Planning and organizational methods in the mining system of stabilization of the material composition of poor copper-nickel ores can significantly reduce the variability of the quality of underground mine products and provide conditions for increasing the completeness of extracting subsoil reserves. |
