Borehole GPR investigations from underground for mapping the extension of old working at a Pb-Zn Mine in Rajasthan, India

S. Nelliat, Babu B Butchi, P.C. Jha, Y.V. Sivaram, Verma SN, Dutta S, Jha A
Conventional GPR reflection surveys in base metal sulphide mines are sometimes marred by scattering due to heterogeneity or presence of disseminated sulphide minerals. Surface scanning in such areas have its own limitations as the depth of investigation is adversely influenced by the highly lossy medium....

Influence of geophysical judgement and software parameters on interpretation of seismic section

V.R. Balasubramaniam, P.C. Jha, Babu B Butchi, S. Nelliat, Y.V. Sivaram, K. Goverdhan
Seismic refraction has long been adapted for various types site characterization studies. The method has evolved from the classical theory based on Huygens's principle involving straight propagation paths representing spherical wave front heading direction into many novel considerations involving curved-ray-path...

Overview of seismic monitoring and assessment of seismic hazard based on a decade of seismic events

Jennifer Praveena Das, V.R. Balasubramaniam, Kantepudi Goverdhan, G.P. Ganapathy
During mining activity, the natural equilibrium of the rock mass gets altered resulting in increase in stress causing sudden, violent failure of rock mass. The stress increases with increase in the depth of mining. The dynamic stress changes caused due to release of strain energy from within the rock...

Foundation Evaluation of a Barrage using Geophysical and Geotechnical Investigations

Babu B Butchi, P.C. Jha, S. Nelliat, Y.V. Sivaram
Geophysical investigationsprior to constructions stage are often met with difficult site conditions particularly over shallow water bodies. Due to site constraints, standard data acquisition procedures, either onshore or offshore may not be suitable in such cases. In this situation designing of site...
