Investigation of Disturbed Rock Zones in Open-Pit Mine Walls by Seismic Tomography

Abstract:

The paper presents the results of measurements of compressional and shear wave velocities in the near-surface zone in the Zhelezny open pit mine, the Kovdor GOK (Kovdor Mineral Producing and Processing Company). Data on the seismic wave velocities are used to estimate Young's modulus and Poisson's ratio. Poisson's ratios derived from the compressional-to-shear velocity ratios are used to locate fractures that are due to stress redistribution and weathering processes in the stepped walls of the open pit mine.
