Abstract

The seismic observations of dumps at Mikhailovsky GOK open pit mine are carried out during mass blasting. The curves of the acceleration amplitude and velocity of vibrations in a blast-induced seismic wave and the reduced distance are plotted. The dynamic stability of the overburden dumps is estimated. It is shown that at certain reduced distances, multiple seismic effects of mass blasting can lead to the loss of the dynamic stability of the dumps. The results are applicable in mass blasting design and in location and parametrization of overburden dumps.
