Verification of kinematic expression for pendulum waves based on the seismic measurements in terms of the Tashtagol Mine and Iskitim marble quarry

摘要

Obtained in underground excavation in Tashtagol Mine, Kemerovo Region, and in dislocation area in karst in Iskitim marble quarry, Novosibirsk Region, the experimental data give evidence of the change in the velocity of seismic wave packets depending on energy of mechanical impulse inputs when elastic waves propagate in the system of mineral body-fault zone-mineral body. It is shown in the article that the resulting dependences between first arrivals of seismic wave packets and energy of impact (source) conform with the kinematic relationship typical for pendulum waves in high-stress structured geomedia.
