Impact of Massive Blasts on Stability of Tectonic Faults

The measurement data on seismic load parameters induced by massive blasting carried out in surface and underground mines are presented. The maximum amplitude of seismic vibrations at the probable depth of potential sources of high-magnitude stimulated-tectonic earthquakes is calculated. These estima...

Summary:The measurement data on seismic load parameters induced by massive blasting carried out in surface and underground mines are presented. The maximum amplitude of seismic vibrations at the probable depth of potential sources of high-magnitude stimulated-tectonic earthquakes is calculated. These estimates and their comparison with the precision deformography observations show that residual displacements along faults at seismic depths under the impact of massive blasts in surface mines are not more than dens-hundreds microns. The seismic data demonstrate insufficiency of these impacts for initiation of high-magnitude earthquakes.
