Estimations of cutting-tool wear and rock-breaking efficiency during underground excavation and geo-energy extraction rely mostly on Cerchar abrasivity index (CAI) tests. However, the measurement of rock abrasivity may not be accurate for highly cracked rock after extreme treatment conditions (e.g.,...
