Purpose. To develop a comprehensive model of a mining enterprise, to define types of models for mathematical modelling at all management levels, and to determine principles and approaches to the formation of new input data concerning both technologies and their subsystems while combining the technologies. Methodology. To achieve the goal, a systems approach is used, which allows selecting the types of models for modelling the enterprise activities in terms of technologies and subsystems and determining the method of generating own input data for them. For this purpose, the following was completed: the available literature and patent sources were processed and generalized; scientific and technical papers on the selection and application of the varieties of models in mining were analyzed; the principles and individual approaches to the input data formation for mathematical modelling were considered. That makes it possible to select a software mechanism and create simulation models for effective management of a mining enterprise. Findings. Types of models for mathematical modelling at the operational, tactical, and strategic levels of enterprise management were determined and substantiated. Connection between the types of models used by management levels was specified. An expert survey for modelling at the operational level, simulation modelling at the tactical level, and dynamic programming at the strategic level of management were selected. A schematic diagram of modelling of a mining enterprise, whose structure included technologies and their subsystems at various management levels, were developed. The principles of input data formation to model all subsystems, either operating or being prepared for their implementation, were studied. The authors own approaches to the input data formation at the levels of management and technological subsystems were defined. Originality. While performing a particular solution of the discrete problem by Bellman method, dependences of minimizing the operations for enterprise management while forming a technological chain of a mine, provided meeting the requirements of production process continuity, were obtained. These studies are aimed at establishing a complex information system with its division into elements, each of which is then used to simulate the whole mining enterprise. Practical value. It means developing a comprehensive model of a mining enterprise, determining the types of models for mathematical modelling at all management levels, establishing a new way of input data formation in terms of both technologies and their subsystems with the implementation of additional mineral-mining technologies.

Purpose. The research aims to analyse and systematise the mineral-raw material base of backfill materials and backfill methods in the Kryvyi Rih Region based on the study of sources of industrial waste accumulation and types, as well as specifications of backfill technologies. Methods. To achieve the purpose set, an integrated approach is used, including a generalisation of world experience in the use of industrial waste as backfill materials, a study of the register of waste accumulation sites in Dnipropetrovsk Oblast, schematization of the geospatial location of the mineral-raw material base of backfill materials using Google Earth, systematisation and classification of possible backfill methods and combinations of backfill mixture options. Findings. It has been determined that the mineral-raw material base of backfill materials in the Kryvyi Rih Region is insufficiently studied. The scheme of geospatial location of mineral-raw material base sites of backfill materials in the Kryvyi Rih Region has been developed. A general assessment of information data of existing types of backfill materials, their functional purpose, sources of formation and resource reserves is provided. Classification of possible combinations of component backfill mixtures in the Kryvyi Rih Region by types of backfill technologies is proposed. Originality. For the first time, the existing mineral-raw material base of backfill materials in the Kryvyi Rih has been systematised, and a classification is proposed of possible combinations of the backfill mixture component composition by types of backfill methods. Practical implication. Operating the available mineral-raw material base and possible types of backfill methods gives reasons to consider a wide range of resource-saving technologies to minimise geo-ecological problems in the Kryvyi Rih Region. Keywords: mineral-raw material base, backfill material, backfill technology, systematisation, classification.
