Key outcomes from the testing and investigation program
- Were the failed and currently intact splices prepared in accordance with the splicing procedure in the belt manufacturer’s splicing manual?
- Were the parent belts manufactured in accordance with the relevant Technibelt specifications or Australian Standards?
- Did the quality of the parent belt contribute to the splice failure? Will the quality of the parent belt contribute to the possible future failure of belt and splices currently installed on the conveyor?
- Did the quality of the splicing materials, workmanship and process contribute to the splice failure? Will the splicing materials, workmanship and process contribute to the possible future failure of splices currently installed on the conveyor?
- Did any existing splice repairs contribute to the failure of the splice? Will any repairs to existing splices contribute to the possible future failure of splices currently installed on the conveyor?
- Did an isolated event contribute to the splice failure?
- Did the operation of the conveyor contribute to the splice failure? Did the operation of the conveyor exceed any maximum design parameters? Were any conveyor safety systems overridden and contribute to the splice failure?
Belt & Splice Failure Projects
Belt & Splice Failures – Hard Rock Mine in QLD
Technibelt was commissioned to investigate a ply belt splice failure at a hard rock mine in QLD. The splice had been extensively repaired on the top and bottom covers. An existing top cover repair had failed and was exposing the pocket of delamination through several steps of the splice ...read more →
Belt & Splice Failures – Coal Mine in NSW
Technibelt was commissioned to work closely with the maintenance and reliability teams at a coal mine in NSW to radically decrease downtime caused by conveyor belt and splice failures. The modern conveyor systems were designed on the lower limits relating to pulley diameters and belt/splice factors of safety. The ...read more →
Belt & Splice Failures – Underground Coal Mine in QLD
Technibelt was commissioned to investigate ongoing solid woven finger splice failures at an underground coal mine in QLD. The full belt width transverse failures occurred in parent belts within the prepared section of the splices but outside the fingers. Independent laboratory testing of the parent belt found the belt ...read more →
Belt & Splice Failures – Hard Rock Mine in NT
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 ...read more →
