dc.description.abstractOne of the most commonly used methods of determining the rock abrasivity is Cerchar Abrasiveness Index (CAI). The basic parameters affecting abrasiveness are density, cementation degree, strength properties and the number of abrasive minerals in the rock. In this study, 20 different tests were carried out on 80 different rocks, mainly Young's modulus (E), uniaxial compressive strength (UCS) and CAI. The main aim of the study is to estimate the basic mechanical rock properties which are difficult to determine and time-consuming with the help of CAI values. In addition to simple equations, multiple regression equations were developed using CAI and other test methods (11 tests). Among the obtained equations, the most reliable ones were determined with the help of a developed performance index (PIat1). The results of the study show that there are significant relationships between basic mechanical rock properties and CAI.
