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

Autonomous Haulage Systems (AHS) are considered a cheaper, safer, and more reliable option to run the mines by mining companies, especially those in the Americas, Australia, and Europe since the cost of the workforce is high or there is an increased risk in the terrain. In addition, autonomous haulage systems will improve efficiency and ...

In these projects, the boring machines drill through rocks characterized with different properties. In coal mines, coal is one of the major types of sedimentary rocks with low uniaxial compression strength (UCS) (<120 MPa). The drilling depth in coal mines can reach 600 m, and the maximum diameter of back reaming reaches 5 m.

In 1994 the first autonomous haul truck trial (a 777) occurred at a Texas Crushed Stone quarry in the US. At a similar time, were trialling autonomous HD985 haul trucks at Alcoa in WA. Now we have around 500 autonomous haul trucks in the mining industry, predominantly in the iron ore mines of Western Australia.

Automatic truck loading and unloading systems have become the ideal solution for improving agility and safety during the goods receipt and dispatch process at the warehouse docks.. The loading docks are a vital part of any distribution more docks an installation has, the greater the goods flows or, in other words, the number of trucks that enter and leave the warehouse.
