METHOD AND SYSTEM FOR EVALUATING RISK OF HIGH-ENERGY SHOCKS CAUSED BY UNDERGROUND DEVELOPMENT Russian patent published in 2016 - IPC G01V1/00 G01V9/00 

FIELD: geophysics.

SUBSTANCE: invention relates to geophysics and can be used for evaluation of high-energy shocks. Disclosed method comprises measuring vibrations (E^pomI) on surface of three-dimensional vibration sensors (4) and measuring parameters of shocks (E^pomII) under ground using mine seismic system localisation shocks (12), as well as measurement of displacement (U^pom) on surface using three-dimensional displacement sensors for points of surface (9) with periodic correction tachometric measuring set (B). Obtained data are subjected to analytical processing circuit (2a) and forecast of high-energy shocks in spatial-time continuum by estimation of critical events, considering alignment of observations in form of quasi-deterministic and space-time extensive process of deformation of rock mass, as well as paraseismic phenomena in form of short-term vibrations of particles of rock mass in aspect of time and frequency. System consists of measurement data processing centre (1), where there is translation server (2), which is connected to wireless communication modem (5), analytical circuit (2a), as well as shaft seismic network localisation shocks (12), which is a wire link is connected with seismometric sensors (11). In its turn on monitored section of rock mass (15) measuring sets (A), while in section, not exposed to deformation under effect of shaft development, there is a tachometric measuring set (B), which is connected to a satellite navigation system receiver of tachometer (3), as well as wireless communication modem (5).

EFFECT: technical result is higher accuracy and reliability of forecast data.
