Determination of rockmass quality by the crosshole seismic method
Summary The purpose of the method is to map velocities of P- and S-waves, elastic moduli and attenuation coefficients in the region between two boreholes. The results can also be used to determinein situ mechanical properties of the rockmass and to locate cracks, fractured zones and ore bodies. The seismic excitor is basically a hammer driven by a spring against an anvil clamped in a borehole. The receiver probe includes three accelerometers positioned at right angles. A reconstruction algorithm is applied and local values of P- and S-wave velocities are assessed at every point of a grid superposed on the survey plane.
