Regularity of particle velocity decrease with scale d distance for rockbursts and shot holes

Original language description

The paper is intended as an analysis of particle ve locity generated during rockbursts in deep coal min es in the Ostrava-Karviná Coal Basin (OKCB), which are recorded at five undergroun d seismic stations. On the other hand, we realized field measurements in open-pit coal and shale mines in northwestern and central Bohemia in the course of blasting operations. Based on ana lysis of experimental data it was proved that the slope of straight regression lines n of peak ground motions for rockbursts variesbetw een values of n = - 0.8 up to - 1.5, while n = - 1.8 up to - 2.5 were found for explosions in holes. While the monitoring system in the OKCB is i n a continuous operation using three- component seismometers WDS-2, a massive seismometer VBP-3, whichenables us to record ground motions i n the near zone of the explosion, was occasionally used for experiments in open-pit mines.
