Abstract

The estimates of the Q-factor parameter based on the registration of the amplitudes of P- and S- waves along the profile of the «Mikhailovsky» quarry – «Mikhnevo» SAA from two quarry blasts were obtained. The registration was carried out by three-component sensors, which made it possible to estimate the Q values by three components. Two methods were used – the estimation of the amplitude attenuation coefficient and the ratio of the amplitudes of the spectral components depending on the distance. These two approaches were widely used earlier for the interpretation of the deep seismic sounding (DSS) data. As a result, the average values of the Q-factor parameter were obtained by two methods – Q for P-waves is about 376 and for S-waves: Q = 1068 and Q = 897
