PRINCIPLES OF SUSTAINABLE DEVELOPMENT OF MINING AND TECHNICAL SYSTEMS IN TRANSITIONAL PERIODS

The relevance. Functioning of mining operations in modern conditions is characterized by the active influence of external and internal factors. In the conditions of the unstable external environment, upon transition from one development stage to another, subsystems of mining operations have to submit to the purpose of ensuring steady functioning of the enterprise – providing output streams with the set parameters. During this period stability of mining and technical systems changes that have an impact on a condition of economic and social subsystems of mining operations, and also on the state of environment caused by changes in parameters of technology and engineering procedures. It demands the development of the new approaches and the management principles of work of the mining operations based on coordination of economic targets with the purposes in the field of ecology and social development. The main aim of the research is to form sustainable development concept of mining and technical systems in transitional periods of open pit mining based on systematization of the existing principles of sustainable development in the mining industry. Objects: mining operations, mining and technical systems, opening-up system of opencast. Methods: literature review, structural and functional analysis, system analysis. Results. The paper substantiates the key role of the opening-up system of opencast in the structure of the mining and technical systems for achieving sustainable development goals of the mining operations. The systematization of the sustainable functioning and development principles of the mining operations and their systems were carried out, four groups of principles were highlighted: system-wide principles of management, development principles of the mining operations, development principles of mining and technical systems, development principles of the subsystems of mining and technical systems. The idea of consecutive transformation of the subsystems of mining and technical systems at all design stages and operation considering economic, social and ecological aspects for ensuring the established parameters of functioning of the mining operations is the basis for the offered system of the principles. The authors proposed the concept of sustainable development of mining and technical systems in transitional periods of open pit mining. The use of the proposed approach during transition from open pit mining to the open-underground mining allows us to improve the economic, environmental and social indicators of the functioning of the mining operations systems.
