Geological wear factors in a hole are currently being studied since the type of soil, as well as the lack of knowledge of its composition, have a significant impact on the wear of diamond drill bits. Abrasive materials in rocks and valuable metal occluded aggregates reduce bit life. In the present work, drill bits with diamond embedded in the matrix are tested in two deposits, Zona Dolores Y18 and Zona Cobriza C12, where the semi-fractured granodiorite intrusive is variable in both deposits, for such evaluation the model of pure abrasion and isotropic wear was resolved. This model showed that the variation in the amount of semi-fractured granodiorite impacts the performance of the drill bits with a drilling of up to 20m, which represents a reduction of up to 8 hours in the drilling work.
