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.

The prospect of mining the majority of deposits in the Far Eastern region is associated with the need to switch from the open-pit to the underground method of developing deep-lying ore bodies. Ensuring the safest conditions for the combined development of the field is possible only after comprehensive studies have been carried out that make it possible to establish the peculiarities of the formation of the stress state in the rock mass taking into account the influence of various natural and technogenic factors. An assessment of the stability of structural elements of the proposed development systems at the deposits will allow identifying potentially impact hazardous areas and developing measures to maintain and protect mine workings, which will reduce the risk of dynamic manifestations of rock pressure.
