Investigation of the Relationships between Mineralogical and the Engineering Parameters of Rocks

Abstract

This study focuses on the investigation of the relationships between physical parameters (cohesion (C), internal friction angle (), unit weight (UW), ultrasonic P wave velocity (UPV)) and pyrite content (Py, %) with rock strength (UCS). Polished section analyses of rocks were performed via Clemex image analysis system and motorized table which are integrated into the trinocular research microscope that is a modern technique. Correlation analysis was performed between UCS and Py. Statistically significant relation wasn't obtained between the data pairs even though coefficient of correlation is relatively high (r=0.69). However, a statistically significant relationship (with p=0.003 and F=302.6) was achieved with high coefficient of determination (R 2 =0.936) when multivariate regression analysis was carried out between UCS and other parameters including "Py" used in this study.
