Abstract
This project looks at Estimating some mechanical properties of rock from in-situ rebound values. The research deals with estimating some mechanical properties of rock from in-situ rebound value in Oreke open pit quarry, N-Type Schmidt rebound hammer data were collected from Oreke open-pit .the data were collected with the view to ascertain the suitability of Schmidt hammer for quick, cheap and less cumbersome estimation of the uniaxial compressive strength of marble. The data collection was strictly carried out by ASTM and suggested equation by different authors. Uniaxial compressive strength, density, young modulus were determined using value conversion graph. uniaxial compressive strength for location 1 was 70MPa which mean the rock is medium in classification and location 2 and 3 was 55MPa this implies that is medium in term of strength, a type is a competent metamorphic rock..
