Abstract
Problem Statement (Relevance). The long period of deposit development and constantly changing market conditions lead to the need to revise design and organizational-technological solutions, including the technical and economic justification of new conditions, revision of reserve volumes, productivity, product quality requirements, as well as types and models of used mining machines and equipment. In this regard, for existing and designed mining enterprises, it is necessary to develop a scientific and methodological base for determining the parameters of the mining engineering system and managing them at the stage of operation during the comprehensive transformation and development of a subsoil site. Improving the methodology for accounting for the influence of internal and external factors of the development of mining engineering systems on the dynamics of open geotechnology parameters is an urgent scientific and practical task, the solution of which will ensure the sustainable functioning of mining enterprises in changing mining engineering conditions and the mineral resource market situation. Objectives. Development of a methodology for managing the parameters of a mining and technical system in the dynamics of open-pit mining development to ensure the sustainable operation of a mining enterprise in changing mining and technical conditions and the situation on the mineral resource market is required. Methods Applied. This work uses a comprehensive approach to research, which includes: scientific generalization of Russian and foreign experience in increasing the efficiency of subsoil development using open geotechnology; simulation modeling of mining system parameters; statistical processing of research results; comprehensive technical, economic, and structural-functional analysis. Result. The article presents a methodology for managing the parameters of a mining engineering system, which includes: analysis of external and internal influencing factors; establishing the possibility of changing the main indicators of the system and determining the range of their values, which in combination ensure an increase in the complexity and efficiency of development of a subsoil area for specific mining, geological and market conditions, taking into account the territorial location of the enterprise; determining the values of the system parameters, which in combination ensure the receipt of the required indicators; assessing the combination of parameters and indicators based on determining profitability and standard deviation; calculating the integral indicator, according to the maximum value of which the selection of parameters is carried out.
