Purpose. To conduct an analysis of the mining and geological features of the occurrence, the current state of development and the establishment of optimum parameters of the Pinyazevytsky granite deposit mining system elements. Methodology. Analytical, statistical, grapho-analytical, experimental research in the conditions of operating quarries, technical and economic analysis and forecasting were used during the research. Findings. The conducted research made it possible to analyze the mining and geological features of the occurrence and the current state of development, the analysis of the Pynyazevytskyi granite deposit mining system was carried out and their optimal parameters were substantiated.The average thickness of the mineral is 100.3 m. On the basis of the mining and geometric analysis of the quarry field, the average exploitation ratio of the overburden on the deposit was 0.07 m3/m3. Based on the calculations, the following parameters of the field development system elements are determined in the work: the minimum width of the working platform during the development of rock and dead-end dump truck turning is 27 m, and when the dump truck turns in a circle – 34 m; the width of the working area when working with rock and using the EKG-5A excavator is 51 m. The calculated maximum permissible height and slope angles of the ledges are: height of the ledge 15 m; the slope angle of the working ledge is 80°; the angle of stable slope is 75°. The width of the working area during the development of loose excavated rocks is calculated using the Volvo EC-240 excavator and is 39 m with ledges 5 m high. Originality. Conducted an analysis of the current state and features of the Pynyazevitskyi granite deposit development, substantiating the optimum parameters of the mining system elements for the open-pit mining of industrial mineral deposits. Practical value. The results of the research made it possible to establish the characteristic features of the mining enterprise, which significantly affect the mining of mineral deposit and the establishment of optimum parameters of the mining system elements for the mining of industrial raw materials for the production of aggregates.

Purpose. Industrial minerals mining technology justification using mobile crushing and screening plants. Methodology. Analytical, statistical, graph analytical methods and experimental research were used on working quarries. Findings. The research made it possible to establish the influence of the migmatites mining technology by mobile equipment on the capacity of the extraction-loading and transport equipment. The following conclusions can be made based on the studies of the complex influence of the factors of the industrial minerals mining technology by mobile equipment on the example of the Odarivsky deposit of migmatites. Using mobile crushing and screening equipment located in the quarry allows for increasing Excavator Productivity for loading crushers' hopper at 16.7% compared to the loading in haulers and increases the productivity of haulers at an average of 25% compared to the cyclic technology in which the crushing and screening equipment is located on the surface, and haulers carry out the transportation of raw material from the quarry. The increase in the productivity of mining transport equipment is achieved due to the absence of downtime of the excavator while waiting for haulers and the maximum use of the vehicle's load when transporting finished crushed stone products with a high bulk density. Originality consists in establishing the peculiarities of industrial minerals mining and establishing the dependences of changes in the productivity of mining transport equipment when using mobile crushing and screening equipment directly on the working sites of the quarry. Practical value. The results of the research made it possible to justify the complex mechanization of the cyclic technology of raw material extraction with the use of mobile crushing and screening equipment for the application in Odarivsk migmatite deposit, which increases the efficiency of the use of extraction and loading equipment and haulers, which ultimately reduces the need for transport equipment and improves the efficiency of the mining as a whole during the industrial minerals mining for the production of aggregates.
