Technibelt was commissioned to investigate high belt change rates associated with total/imminent splice failures at a hard rock mine in NT. Independent laboratory testing of the splices found significant issues with splice workmanship and process control. However, laboratory testing of the parent belt found the belt specifications were the major cause of the premature splice failures and belt changes. Technibelt developed site and conveyor specific belt specifications and belt splicing quality assurance documentation. Belt purchased and spliced against the correct technical specifications and verified by independent testing ensured quality belt installations. Belt changes are now scheduled due to cover wear and/or cover wear/impact damage.
