AB - The assessment of abrasiveness and hardness of rocks have been extensively coveredby previous researchers, with little attention to flints, which were only described as highly abrasive.However, analysis of flints has shown that abrasivity of flints varies. These parameters areimportant inputs for the prediction of drill bit wear rate and design of various parts ofdrilling/tunneling/mining equipment. In this paper, a classification of flints (sampled from theEnglish, French and Danish Chalk) which correlates with the abrasivity and hardness of flints isproposed. The results showed lighter/grey flints (with more calcite) have lower potential to causedrill bit wear as indicated by hardness and geotechnical wear indices than dark flints. This tends tosuggest that even small variations in the carbonate content results in significant variation inabrasivity and that colour can be used as an indication of the potential of flints to cause tool wear.
