Equivalent relations between indicators of underground development of ore deposits

Introduction. In connection with the development of an underground method for the development of mineral deposits and the need to combine both the principles of resource and nature conservation, the indicators of the ecological and economic efficiency of ore mining technologies need to be comprehended. It becomes necessary to rank the interaction of the development indices of a particular field. Goals and objectives. The aim of research in the field of mining is to prioritize the optimization of the methods of development and technological processes of extraction and processing of ore deposits by the criterion of completeness of subsoil use, and ranking of the underground development indicators from the standpoint of their equivalence within the framework of a unified system is given the status of a task-relevant for the development of the mineral resource base. Methods. The solution of the problem involves modelling the parameters of the technology using mathematical programming methods with objective functions to find the compromise optimum of the technical and economic indicators of mining production within the framework of the dynamic model of managing production processes. Results. The experimentally obtained dependences of profit from dilution, on operating costs and on damage at loss of ore at all stages are presented. The quantitative values of the equivalence of loss of ore and dilution by the surrounding rocks, rocks within the ore body, the productivity of the worker's labor in the cleaning works, the productivity of the block and the productivity of the working mining department are given. The results of the economic and mathematical modeling of variants of the development technology with a different share of the filling of process cavities are presented. The estimation of variants of development of a concrete metal deposit is given by comparing the optimum values of the target functions. It was confirmed that compensation for dilution at the ore dressing stage has the strongest impact on costs. The conclusion. It is concluded that the main condition for increasing the efficiency of mining deposits is the reduction of losses and dilution of mineral raw materials, including by implementing the results of mathematical programming by the criterion of optimality, taking into account the damage from losses and dilution, and by establishing equivalent relationships between quantitative and qualitative indicators of field development.
