ALGORITHMIC PROVISION OF HAZARDOUS AREAS OF ROCK MASS

Abstract

One of the approaches to forecasting the dynamic manifestations of rock pressure is the method for monitoring the seismoacoustic active zones, which consists in identifying and analyzing the dynamics of formation of acoustically active zones and in forecasting the impact hazard on the basis of established patterns for changing the geoacoustic activity of the rock mass. The key point of this control method is the identification of a zone within
which a potentially hazardous source of rock destruction is formed. This paper proposes the automated method for identifying the focal zones based on preliminary exclusion of background radiation by method of non-parametric density estimation, allocation of seismoacoustic active
zones by means of probabilistic cluster analysis and parameterization of focal zones by selection of characteristic ellipsoid. The solution of the above tasks within the framework of the development of the system of comprehensive geomechanical monitoring by modernization and subsequent integration of the considered method of control of seismoacoustically active zones into the accompanying software will allow to fully automate the process of forecasting the hazardous state of the controlled rock mass, increasing the quality of the forecast and significantly reducing the time taken to obtain the final result.
