The abrasiveness of soil and rock is a determining factor for tool wear in all processes of rock excavation above and below ground, for example drilling, cutting and excavating. Although this is highly cost‐relevant, no classification scheme has yet been produced, with which soil and rock can be classified according to their abrasiveness and wearing effect. Comparative investigations using three methods of determining abrasiveness were used to produce a proposal for the classification of rock material. Although further series of investigations still have to be performed, a classification scheme has been produced, which is already in practical use and could be of use in future projects.
