Conclusions
It is apparent that there is no single index that can provide a comprehensive measure of abrasiveness of rock material, but the range of tests described in the paper can provide an assessment of the overall abrasiveness of rock in conjunction with other physical properties. However, it is necessary to devise specific tests to suit a particular mode of excavation taking all these factors into account. Some subjective judgement is also necessary. These investigations can prevent costly mistakes in equipment selection and possibly assist in identifying alternative excavation systems.
