Abstract. The article covers a live problem of mismatch between parameters of technologies, processes and mining equipment, which results in an inefficient use of machines, their rapid wear and tear, and uneconomical ore extraction from the deep horizons of the quarries.

Parameters of such processes as blasting, excavation, mechanical crushing and transportation of the rock mass are analyzed in the article with taking into account the job sequencing and complexes of currently used equipment. The basic relationship between successive processes and necessity of their mutual adaptation is formulated.

It is shown that in case of no additional spacing between the pit walls, parameters of currently usedtransport equipment restrain further advancing of mining operations into the depth, and therefore, it is recommended to improve the equipment in order it could operate in the restricted space.

Keywords: quarry, technology, processes, mining equipment, parameters, particle-size distribution.
