Geostatistical Integration of MT and Borehole Data for RMR Evaluation

P117 Geostatistical Integration of MT and Borehole Data for RMR Evaluation B.S. Suh* (Kangwon National University) S. Oh (Kangwon National University) & Y.I. Kim (KIGAM) SUMMARY We apply the geostatistical approach to integrate MT resistivity data and borehole information for the spatial RMR (Rock Mass Rating) evaluation. Generally resistivity of subsurface has been believed to be positively related to the RMR and here we combined the resistivity and borehole RMR information by geostatistical approach. To relate the two different data we take the MT resistivity data as secondary information and estimate the RMR means at unsampled points by correspondence of
