    Investigation of ground velocities during rockbursts

  • Original language description

    This paper presents partial results of the ground velocities analysis which were observed during the rockbursts at three underground seismological stations situated in the Ostrava-Karviná coal mines. For the investigation records of 49 rockbursts were used, energy of which was within the range of 103 - 107 J and hypocentral distances varied from 500 to 6900 m. Using the method of linear regression, dependences for ground velocity ui vs. scaled distance rred for P and S waves were derived which were expressed by following equations: Pmax -waves ui = 1.243x10-4 * rred-1.016 (m.s-1) Smax -waves ui = 5.167x10-4 * rred-1.185 (m.s-1) interrelations between individual parameters, i.e. ground velocity, hypocentral distance and seismic energy a nomogram was constructed. From experimental measurements implies that prevailing frequencies of P and S waves occur within the frequency bands of about 3 - 12 Hz and 2 - 6Hz, respectively.
