Abstract

Electrical resistivity values of eight different samples cored from a fault breccia were measured using all impedance analyser. The uniaxial compressive strength, elastic modulus, point load strength, Schmidt hammer Value, P-wave velocity, density and porosity values of the samples were determined in the laboratory. Electrical resistivity values were correlated with the corresponding physico-mechanical properties using the method of least-squares regression and the derived equations were checked by the t and F-test. A strong logarithmic relation between uniaxial compressive strength and resistivity was found. The relation between elastic modulus and resistivity is significant and follows a logarithmic function. Density was linearly, and porosity was exponentially correlated with resistivity.
