| Summary: | This paper is based on a study carried out at Aitik Boliden mine in Gällivare in the spring of 2008. At the Aitik mine there are a number of electric rope shovel machines used for loading both ore and waste rock onto trucks. During loading and hauling of ore to the truck teeth/adapters from the bucket sometimes undetected break off. The undetected tooth follows the truck to the crusher where it causes jamming resulting in significant repair cost and downtime for the mine production. This thesis focuses on a method to prevent the teeth/adapter from ending up in the crusher Based on an Infrared detection system that reads the bucket profile every time it hauls the ore onto the truck. Also other detection system available on the market has been studied and a probable preventive maintenance program suggested. This thesis explores different solutions to the above problem and provides a basis for future research in this field. Validerat; 20101217 (root) |
