Abstract
Vertical shafts at the underground Pongkor gold mine were developed using a raise boring of Robbins 73RM DC. Assessment of the raise boring cutting performance was carried out in the Ciurug Raise Boring II, at three levels, such as 40 m, 70 m and 100 m. Core rock samples for laboratory tests were obtained from these three levels to determine the physical and mechanical properties. Relationship between cutting production againts toughness index or specific cutting energy and also its relationship with RMR are discussed and established
