Abstract

Central Institute of Mining and Fuel Research, Nagpur carried out the study of “Raippability Assessment of Rock Mass at an Iron Ore Mine in Karnataka” by using seismic profiling techniques. The study ws conducted with a view to avoid the Environmental effects to the surrounding Senssitive Structures as a result of drilling and blasting. The refraction seismic survey was conducted on all the 4 benches of the mine to determine the compressional (P-wave) wave velocity, which has got the established correlation with rippability. The Refraction seismic survey was conducted to aid in the evaluation of the rippability of the subsurface material (Iron Ore) of the mine. The state of the art instrumentd Geode (Make: Geometrics controllers Inc., USA) was used for acquiring the seismic data and the method of profiling carried out was refraction seismic survey. The in-situ P-wave velocity obtained from all the test sites was in the range of 2000-3000 m/s, which was rippable as per the guidelines provided by the standard Ripper-Dozer manufacturers.
