Automation of load haul dump machines
2011 (English)Report (Other academic)
Load Haul Dump (LHD) vehicles are used in underground mines to load and transport ore and minerals. They can be manually or automatically operated. With an automatic system, the operator can be taken out of the mine and simultaneously control up to three LHDs, thus increasing both productivity and security for the personnel. There are a number of operation modes available for Load Haul Dump (LHD) vehicles and there are many criteria to consider when choosing the best one. This report fills a gap in the literature by mapping and describing the experiences and present status of the operation and maintenance of both automatic and manual LHDs as well as the existing navigation systems and techniques associated with underground automated loading and transportation.The commercially systems available today for automation of LHDs are supplied by Sandvik, Caterpillar and Atlas Copco. Automation focus have over the years gradually shifted from having fully automated fleets of vehicles to more flexible solutions with semi-automatic LHDs gaining safety as one of the main goals. Several issues must be resolved to maximize the benefits of automation. One is to improve maintenance, as this is crucial for an operation to work smoothly without the waste incurred by unplanned breakdowns.
