Introduction. At the present time, the development of geoacoustic signalling safety systems becomes more relevant due to larger production units at mines and higher speed of mining. Such systems include instruments for rockburst hazard assessment based on computer appliance with the use of geoacoustic methods.
Research aim is to develop a range of characteristics of the existing equipment for local monitoring of rockburst hazard Prognoz L. The approach considered in the work should allow locating the sources of acoustic emission, provide wider range of working frequencies, and enlarge marginal massif control zone. As an additional advantage, it is suggested to increase comfort of use while interacting with the graphical user interface providing many additional features.
Methodology. The present research considers design solutions over the creation of universal measuring and analytical platform for rock mass investigation. The device under consideration is introduced as a substitution for the well-proven Prognoz L local control device, inheriting and enlarging its functions. New platform creation is conditioned by a number of limitations of an original device built on the basis of a microconroller from the STM32 family using a processor core with ARM architecture.
Results. The considered approach to the design of a rockburst hazard local control device, structural, hardware, and software parts are distinguished, each of them being independent and able to be improved with no need to change other parts.
Conclusions. The use of this approach will allow to define the sources of acoustic emission, increase the effectiveness of measurements reducing the laboriousness of the process of developing and introducing new techniques.

Key words: rock massif; rockburst hazard; local control; acoustic emission; event location; geomechanical monitoring.

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
