STUDY OF CERCHAR ABRASIVITY INDEX AND POTENTIAL .

Abstract: Tool wear is an important parameter in mechanized tunneling and is highly affected by rock abrasiveness. There are numerous tests to identify the rock abrasivity. One of the widely used rock abrasion tests is the Cerchar abrasion index (CAI). This test is used for estimation of bit life and wear in various mining and.
