“…Various methods and tools are applied for monitoring of a condition of testing block 7/10 and for the forecast of hazard manifestations of rock pressure during mining process on the "Integrated Kirovsky" Mine. Tools include the seismoacoustic control system of rock pressure "Prognoz-ADS" developed at Mining Institute FEB RAS and the local "Prognoz-L" device [8][9][10][11][12][13][14][15]. Assessment of a geomechanical condition of the rock massif according to seismoacoustic monitoring with application of the automated control system of rock pressure (ACSRP) "Prognoz-ADS" is one of the most perspective directions of the forecast and prevention of sudden destructions of pillar and mine excavations [8][9][10].…”

“…The portable "Prognoz-L" device is intended for local express assessment of a geomechanical condition of regional parts of the massif and the peripheral sites of underground excavations. "Prognoz-L" is applied both independently and is collateral with the stationary automated multichannel control systems of rock pressure for verification of results of the regional forecast of rock bursts and technogenic seismicity [11][12][13].…”

Results of geomechanical research of burst hazard of the rock mass of Rasvumchorr mineral deposit with application of measuring complex are presented in the paper. Measuring complex includes the automated seismoacoustic system of rock pressure control "Prognoz-ADS" and the local geoacoustic device "Prognoz L". The measuring complex was developed in Mining Institute of the Far Eastern branch of Russian Academy of Sciences. Measurements and the analysis of parameters of the seismoacoustic events reflecting geomechanical processes in the developed massif is the basis for estimation of rock massif burst hazard.

“…3b and 3c). Efficiency of the preconditioning measures was also assessed with the help of the rockbump hazards local control device "Prognoz L", developed by the Mining Institute of Far Eastern Branch of Russian Academy of Sciences, which allows registering various parameters of AE pulses, such as frequency, amplitude, duration, arrival time and others [13]. The local control device "Prognoz L" employs a number of algorithms to identify the impulses of natural acoustic emission against the background of anthropogenic noise.…”

Research has been carried out to study the peculiarities of rockbump hazards and induced seismic manifestations at the Nikolaevskoe deposit, and their close correlation with the tectonic structure of the rock massif has been established. In order to strengthen control over the rock-bump hazard in the TN-3 high-angle fault, in 2019 the observation network was expanded and continuous seismoacoustic monitoring of the rock mass at the deep levels of Nikolaevskoe deposit was organized. Monitoring data is verified by local geoacoustic method using the portable device “Prognoz L”. The results of the monitoring revealed major acoustically active zone with the main amount of seismic and acoustic events recorded during the last 5 years and occurring dynamic rock pressure manifestations. Nikolaevskoe deposit was the site of execution of the industrial experiment on regional discharge of a potentially rock-bump hazardous section of a shock blasting massif.

“…Intensive development of microprocessor and digital technologies has created conditions for development of considerably more perfect geoacoustic portable device ("Prognoz-L") for local monitoring of bust-hazard in Mining Institute FEB RAS in recent years [5]. "Prognoz-L" allows to record a large number of the AE parameters, process and analyze the obtained information.…”

Measurements of parameters of acoustic emission were carried out on a number of burst hazard mineral deposits of the Far East and Transbaikalia. New data on features of phenomena of hazard forms of rock pressure on various sites of the mine are obtained. The technique of carrying out of measurements by “Prognoz L” local monitoring device is developed. Criteria of burst-hazard properties of the rock massif on a number of the mineral deposits, being developed by underground mining, were substantiated.
