Adapted Schmidt Hardness Testing on Large Rock Samples—Kanfanar-South Quarry Case Study

This paper deals with the possibility of using Schmidt hardness test, which does not require much preliminary preparation and is easy to perform, in production commercial blocks a quarry. Previous recommendations for testing rock materials were specifically related tests performed geomechanical purposes. They also referred mostly smaller samples, but has some special features, mainly because they are large samples practically larger areas must be tested. presents methodology terms number position hammer strikes on block, as well application corrections test results way cut. The conducted natural stone from Kanfanar-South quarry, characterized by limestone rocks. show that can applied quarries similar geological structure mining methodology.
