Uniaxial compressive strength (UCS) is a key physical test relevant to iron ore crusher design and rock geomechanics for mining. Tests are typically performed on intact lengths of NQ, HQ, or PQ diamond drill core and record the maximum axial load sustained at the point of failure. The International Society for Rock Mechanics (ISRM) standard terminology for UCS is very low (< 5 MPa), low (5

The uniaxial compressive strength (UCS) of each rock material was calculated by dividing the maximum load (P) subjected on the sample by the original cross-sectional area (A). Hence, UCS = P / A. (1) Size correction factor was applied to samples that do not have the height to diameter ratio of 2:1. According to ASTM 1986, the size correction factor is given by: σ corr = σ i / [0.88 + (0.24D
