A Study of Rock Mass Classification Using Seismic Survey

  Down-hole seismic surveys and cross-hole seismic surveys have been used for rock type classification. For rock type classification, such as soft rock, medium rock, hard rock, and very hard rock, the moisture content effect on wave velocities in in-situ rock mass is considered and a new classification criterion is proposed. With an appropriate rock type classification the volume of each rock type can be obtained by trapezoidal rule of integration. The volume of each rock type can be used for estimating amount of work for ripping and blasting when a construction site is being prepared.
