The LHD includes a front axle and a rear axle, and an articulation in the vehicle between the front and rear axles. A diesel engine is positioned to the rear of the rear axle, and powers a hydraulic pump. A hydraulic motor is positioned forwardly of the articulation, and is hydraulically driven by the hydraulic pump.

Load Haul Dump (LHD) machines are used in underground mines to load and transport ore and minerals. Loading and hauling blasted ore from drawpoint to dumping point constitute a significant portion of the production costs for mining companies. There are a number of operation modes available for LHDs, and there are many criteria to consider when selecting the best one.

This paper describes an autonomous loading system for load-haul-dump (LHD) machines used in underground mining. The loading of fragmented rocks from draw points is a complex task due to many factors including: bucket-rock interaction forces that are difficult to model, humidity that increases cohesion forces, and the possible presence of boulders.
