Laboratory cuttability and abrasiveness tests for prediction of worcable rocks in tunel and mining praxis Authors: J. Vasek, P. Martinec, J. Pinka
Unifi ed methodology for determination of so called decisive properties of rocks defi nition when cutting
tools on cutting heads of tunnelling machines are to be used. Laboratory methods, way of measuring
and assessment of rock cutability, abrasiveness, abrasion resistance of rock are presented. Abrasiveness
according to Czech Industrial Standard ON 44112111 and CERCHARE graphical comparison. Area of
workable rocks defi nition.
