### CORRELATION BETWEEN BOND WORK INDEX AND MECHANICAL

(high abrasion value and low compressive strength) to kwh ton 1 for granite (low abrasion value and high modulus of elasticity). The correlation between the abrasion value(X2) and work index (Wi) is found to be Wi = Ln (X2) + with correlation coefficient of KEYWORDS: Bond work index ± Mechanical properties of rocks ±
