Rock Strength Classification in a Brazilian Iron Ore Mine Using Operational Drilling Variables and Machine Learning
Rock strength is a key parameter for mine planning and operational optimization, but conventional laboratory testing is costly and provides limited spatial coverage. This study develops a methodology for classifying operational rock-strength classes in a Brazilian iron ore mine using reverse circulation (RC) drilling d...
