Keywords: MINERALS, EXCAVATOR, TECHNICAL PRODUCTIVITY, CYCLE, PHYSICAL AND MECHANICAL PROPERTIES OF SOILS, BUCKET, DIGGING TIME The object of research - a quarry for the extraction of minerals, complexes of machines, their parameters and physical and mechanical characteristics of rocks Subject of research: the process of interaction of working bodies of mining machines with rocks when performing basic technological operations. The goal of the work -. increasing the productivity of technological schemes of complex mechanization on the basis of substantiation, influence of structural-strength and physical-mechanical characteristics of rocks on the parameters of quarry transport equipment. Scientific and technical tasks - - to define a quarry and to investigate technological schemes of extraction of minerals with the corresponding schemes of complex mechanization and ways of a choice of the equipment for these schemes; - to investigate the relationship between the choice of mining machines and physical and mechanical characteristics of rocks, in the current quarry; - substantiate the methods of increasing the productivity of mining machines, taking into account the impact of structural and strength indicators of rocks on the processes of interaction and efficiency of the working bodies of machines with the external environment; develop recommendations for an existing quarry to increase the productivity of individual mining machines and integrated mechanization schemes. Results and their novelty - for theory Development of methods to increase the productivity of technological schemes of complex mechanization for a specific quarry based on the existing mining and technical conditions of the enterprise, structural and strength indicators and physical and mechanical characteristics of rocks taking into account the parameters of working equipment of excavators and transport machines condition and service systems.
