A reverse vertical seismic profiling/crosswell seismology (RVSP/CSW) inverse technique that is based on an elastic model has been developed. It is intended to obtain the dynamic mechanical parameters and map the structural anomalies in a solid rock medium around an underground opening. These dynamic mechanical parameters and structural images are used to address the behavioral properties of the rock, for example, stability analysis of a critical region of a tunnel. High quality and high-resolution seismic data are required in such an inverse technique to allow very smallscale (less than 25cm) geo-engineering targets to be suitably investigated and make the inverse algorithm convergent at a reasonable response time. The corresponding data acquisition requirements and physical environmental conditions are carefully considered and discussed.
