Uniaxial Compressive Strength Estimating of Rock samples From Selector Injana Formation Within ( Al Najaf – Karbala ) Area .

Abstract

The study relied on the selection of ( 43 ) samples representing of rock samples from sand stone within Injana formation in ( Al Najaf – Karbala ) area , to determine Uniaxial Compressive Strength by point load test apparatus in order to classification of strength of rock quarrying engineering . It is found that upon the Uniaxial Compressive Strength range between ( 0.72- 15.6 ) MPa that very low strength for quarrying .
