Rock abrasiveness is ability of rock to wear down the working tool during the mutual interaction between the working indentor and the rock in the mechanical rock cutting process. The cutting indentor is worn down during the interaction, which changes its geometric dimensions causing the enlargement of a contact area between the tool and the rock surface. The changes in these …

Abrasion is a process of erosion which occurs when material being transported wears away at a surface over time. It is the process of friction caused by scuffing, scratching, wearing down, marring, and rubbing away of materials. The intensity of abrasion depends on the hardness, concentration, velocity and mass of the moving particles.
