Models and algorithms of choice of development technology of deposits when selecting the composition of the backfilling mixture

Abstract

The analysis of the applied development systems in the extraction of minerals is carried out. The main problems arising during the development of mineral deposits are formulated. A method is proposed that allows solving the problem of choosing a technology for developing a mineral deposit and selecting a rational composition of a filling mixture for given filling parameters. The structure of the methodology includes fuzzy models and algorithms that ensure the processing of large amounts of information, form the significance of environmental factors (organizational, mining and geological, production, technical and economic indicators), design and technological parameters of the development system and allow to establish the main interdependencies between them, which, in contrast to the existing ones, allow assessing the integral indicators of the project already at the first stages of selecting the composition of the filling mixture. A structural representation of a design solution model for the development of a mineral deposit is formulated, built on the basis of a system analysis and formalization of mining, geological, technological and external conditions of the deposit, which makes it possible to provide a comparative assessment of the integral indicators of projects. The information structure of the project variant is also recommended. To consider the influence of each factor in the algorithm, it is proposed to apply the coefficient of significance of technical and economic performance indicators.
