Abstract
This paper introduces the study of Togolese gneiss and granites’ intrinsic properties such as mineralogical composition, density, porosity, homogeneity one the one hand, and their mechanical properties such as resistance to attrition, abrasion and puncturing depth on the other. After the correlation analysis, significant correlations between the mechanical properties of the rocks (Los Angeles and Micro-Deval) and the depth of perforation obtained by the rock drilling test were found, as well as the not significant correlations between the mineralogical composition and the physical properties of the rock were observed. Laboratories test often performed to obtain Los Angeles and Micro-Deval values are expensive and time consuming. For this, the depths (parallel and perpendicular to the foliation planes for the gneisses or two perpendicular planes for the granites) obtained during a rock drilling test will be used to estimate its coefficients (Los Angeles and Micro-Deval). This study, is based on a database of a sample size of 32 to determine the parameters of the multifactorial model of size 6 used for the validation tests.
