Scaling Laws for the Design of Rock Support

Abstract.

—The dynamic loads imposed by rockbursts initiated by remote seismic events are directly related to the resultant ground motions. Consequently, the first step in the design of systems for the support of openings subject to such loading is to assess the ground motion characteristics; i.e., to evaluate the peak particle velocity ppv in the design region. Design scaling laws, relating seismic source intensity (event magnitude, radiated energy or a combination of seismic moment and stress drop at the source) to the peak ground motion characteristics at a target (e.g., a development drift or a stope) some distance from the source, are developed, based upon theoretical considerations and supported by a world-wide database. These scaling laws reflect the most relevant, critical conditions for engineering design.

Key words: Scaling laws, rockburst, induced seismicity, ground motion, peak particle velocity.
