Seismicity in mines due to roof layer bending rozwój / Sejsmiczności górniczej w rezultacie uginania się stropu

Open access

The experience, which has been obtained in Polish mining allow us to conclude that the bending of the roof layer over an exploited seam is one of the most important factors influencing the risk of strong seismic emissions. The seismic consequences of plastic deformations during roof layer bending are discussed in the paper. The linear distribution of seismic shock epicentres and trends in the development of seismic energy and event frequency, are expected before very strong seismic events that greatly increase rock-burst risk.

The proposed model of inelastic deformations allow us to correlate the seismic data and results of mining observations, such as convergence of the roof layer and the changes of wells diameter drilled in the roof layer in assessing the risk of rock-bursting.
