  • In all the mechanical systems rock is fragmented by

    In all themechanical systems rockis fragmented by. In all the mechanical systems, rock is fragmented by crushing and chipping. It is one of the preferred techniques for rock excavation because of the direct mode of energy transfer and minimum energy losses incurred. A sound understanding of the fragmentation mechanism is therefore necessary to improve fragmentation efficiency and the design …

  • Investigating the Influences of Indentation Hardness and

    Indentation hardness and brittleness are the important factors to be considered in the study of rock-like materials’ mechanicalcrushingbehaviors. The brittleness of rock-like materials is defined as the ratio of uniaxial compressive strength to tensile strength in this paper. In order to investigate the influences of hardness and brittleness on rock-like materials’crushing...
