The results of mathematic simulation of the work of a mining company

The economy of Russia is based around the mineral-raw material complex to the highest degree. The mining industry is a prioritized and important area. Given the high competitiveness of businesses in this sector, increasing the efficiency of completed work and manufactured products will become a central issue. Improvement of planning and management in this sector should be based on multivariant study and the optimization of planning decisions, the appraisal of their immediate and long-term results, taking the dynamic of economic development into account. All of this requires the use of economic mathematic models and methods. The object of research is the work of OAO “Uchalinsky GOK” which is the leading plant in the extraction and enrichment of copper-zinc ores in the Ural region. Production capacity is the most important technical-economical indicator established to substantiate the feasibility of exploration and further development of a site for the design of new and reconstruction of old mining processing plants. The optimal production capacity is the capacity at which ore is extracted with the most favorable indicators of workforce productivity, production costs and overhead costs. Applying an economic-mathematic model to determine optimal ore mine production capacity, we receive a figure of 4,712,000 tons. The production capacity of the Uchalinsky ore mine is 1560 thousand tons, and the Uzelginsky ore mine - 3650 thousand. Conducting a corresponding analysis of the production of OAO “Uchalinsky Gok”, an optimal production plan was received: the optimal production of copper - 77961,4 rubles; the optimal production of zinc - 17975.66 rubles. The residual production volume of the two main ore mines of OAO “UGOK” is 160 million tons of ore.
