Реферат | With a brief characteristic of the modern process of integration of Russia in the world economy, the authors present major principles and approaches of generation and implementation of development strategies for companies (plants), in particular, coal mining companies, under conditions of dynamic environment and competition in the world market. In terms of open pit coal mines of SUEK, the article describes variants (types) of development strategies, each characterized with a goal, planning horizon, investment parameters, acceptable risk level, mode of mining and method of safety and efficiency. Based on the strategy accepted by the owner of assets for the open pit mining, optimal parameters of the mine-technical system are determined and recommended: stripping ratios, number and width of work areas, prepared reserves, overburden haulage distance, highwall angle. With any accepted strategy of development, it is required to ensure safety, efficiency and rationality of mining operations. The strategy-consistent levels of production safety and efficiency are provided by concentration and modes of mining operations. The concentration of mining operations is understood as the degree of clustering of mining and handling equipment in work areas with specified parameters. The mining concentration methods in open pit mines are grouped into mine-technical methods, supported by spatial planning solutions and optimized transport infrastructure, and organizationaland-technological methods, backed by increased capacity of mining and handling equipment and smoothed production flow. A rational mode of mining operations is a sequence of execution of assigned volumes of overburden removal and mineral extraction, considering the accepted development strategy. Strategies agree with the following modes of mining operations: maximum mineral extraction and minimum stripping; short-term concentration in areas with minimum stripping ratio and preserved level of production, constant volumes of stripping and actual mining, concentration in areas with maximum stripping ratio if internal and external situations are favorable. To reach and maintain optimal parameters of mining, in addition to technical and technological solutions, it is required to account for organizational factors such as qualification and interoperation of personnel; safe and efficient labor motivation; system visualized item-by-item record and control of effective operation time of equipment and personnel. This aspect contains considerable resources for optimization and mining efficiency and safety improvement, and needs special research into development strategy of production. The authors highlight importance of reliable prediction and modeling of follow-up development for timely generation of sources, assets and reserves in order to ensure implementation of an accepted strategy. |
