Based on the analysis of existing approaches in the prediction of dynamic phenomena of rock pressure, it was established that the basis of most methods is the kinetic concept of the destruction of solids. A team of authors from the Mining Institute of the Far Eastern Branch of Russian Academy of Sciences has developed a method of geomechanical monitoring of a rock massif state, which consists of analyzing the dynamics of the acoustic active zones formation and predicting the impact hazard based on the established regularities of changes in the geoacoustic activity. This paper proposes an automated method for identifying focal zones, based on preliminary exclusion of background radiation using a non-parametric density estimation method, identifying seismoacoustic active zones by means of probabilistic cluster analysis and parameterizing focal zones by selecting a characteristic ellipsoid.

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.

The paper presents a measuring set – a single-component laser strainmeter – for geodynamic monitoring within the Streltsovsk ore field. The results of experimental studies with the participation of a laser strainmeter (deformograph) are presented and the influence of external factors on the state of the massif has been estimated. The influence of distant earthquakes on the state of the mountain massif has been estimated. The features of the deformation field behavior during preparation and implementation of a rock burst have been noted. Characteristics of rock burst precursors in the low-frequency measurement region have been given.
