Introduction. The article reviews the equipment and technology for open mining operations at the largest Russian gold pit Vostochny with the annual ore production capacity up to 15 million tons per year with the depth up to 840 m.
Research theory. Concepts of the technological complex and the pit mine technical system are given. Taking this into account the flowchart which defines the studied object structure is offered. On the basis of integrating practice data and design experience the features of mining-transport equipment kitting out and mining operations key parameters determination are introduced.
Results and conclusions. The results of conveyor systems application evaluation for overburden rocks transportation are presented as well as remotely-controlled drilling rigs, excavators, dump trucks and bulldozers in a deep ore part of a pit. The condition of mining operations is analysed. On the example of schemes, the pit attitude positions and sizes change is shown. It is established that for conveyor transport economic efficiency, the volume of the transported overburden rocks has to be not less than 50% of the ISSN 0536-1028 «Известия вузов. Горный журнал», № 4, 2019 11 general calendar value. At the same time it is possible to place a crushing complex and a reloading point at the edge of an opens pit at a depth of 50 m from surface. The reasonability of equipment remote control systems application is estimated by the possibility to develop edges with the increased slope angel in a deep ore zone of a pit. Such decision allows to reduce the maximum annual volumes of overburden or at their almost invariable value to increase annual ore production capacity to the level of 15 million tons per year.

Key words: pit technological complex; mining technical system of a pit; severe climatic conditions; pit depth; distance of mined rock transportation; ore production capacity; mined rock productivity
