Assessing the physico-mechanical properties of rock is one of the important factors of concern to the engineers in the general field of rock excavation. Different direct and indirect methods are applied to determine the rock properties. This paper deals with the details of a design concept applied to develop a drilling prototype which generates online drilling parameters and can be used to correlate with various rock properties.
