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.
