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.
