Underground—APAC—Australia—Mining Delivering Ground Support Cost Efficiencies: The DSI-PEAK Resin Bolting System In 2015, DSI Australia released the new DSI-PEAK Resin Bolting System to the underground coal mining market. This new system increases mining efficiency through improved ground stability without major changes to equipment or operational practices. The DSI-PEAK System promotes the positive attributes of resin bolting methods while minimising potential technical deficiencies. The system characteristics include: improved resin mixing reliability, reduced gloving, reduced resin pressures, robust pre-tensioning, reduced installation times, 14 high fracture toughness and the ability to re-tension the bolt after installation. The system is a product of all its elements working in concert; that is, the resin matched to the bolt, the increased annulus and the plate size along with the un-encapsulated section of bolt to provide a solid beam in the roof of the mine. Each piece of the bolting system is matched and therefore is sold only as a complete system. The feedback from all mines currently using the system has been positive without exception: They have seen considerable improvement in strata control, paired with benefits in operation efficiency and reductions in secondary support.
