Development of Technology for Seismic Diagnostics of Rock Mass Conditions above the Production Working when Mining Coal Seams Prone to Geo-Dynamic Phenomena

Abstract

Methodical guidelines to receive seismic evidence of console block cracking and hardware for continuous recording of seismic processes are developed. Energy and spectral characteristics of seismic emission for the development of tectonic destruction zones in various rock structures of the upper roof and the ability to display spatial migration of hypocenters of seismic events and their energy scale are determined. The algorithm for computation of diagnostically informative features of geodynamic hazard is worked out.
