Determination of rock mass modulus of deformation by hammer seismograph
Summary Rock mass modulus of deformation is one of the most important input parameters in element calculations for rock mass stability. It can be determined dynamicallyin situ, if phase velocities of the P and S waves and rock mass density are known. The procedure for the determination of these velocities with the hammer seismograph and standard horizontal geophones is described. Results from drifts in two Finnish mines are presented and compared with static laboratory determinations.
