ABSTRACT

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 cumber some 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 which also mean the rock marble medium is classification and typical rock, type is competent metamorphic  rock.
