Approximately, 40% of the total energy used in surface mines is related to diesel consumption. Truck haulage is responsible for a majority of this. This chapter introduces the principal equipment used to load and haul materials in mines, namely trucks, electric rope shovels, hydraulic excavators and crushing and conveying systems.

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 ...

Abstract. Robots are being utilised for mining applications since 1976. However, since 2002, robots are widely into mining from conception to end product or even endusers. Lidar sensors connect robot with a realtime map making it travel safely but detects and avoids obstacles on its own. Autonomous Mobile Robots (AMR) are widely used to ...

To improve the purity of coal and prevent damage to the coal mining machine, it is necessary to identify coal and rock in underground coal mines. At the same time, the mined coal needs to be purified to remove rock and gangue. These two procedures are manually operated by workers in most coal mines. The realization of automatic identification and purification is not only conducive to the ...

To answer the need for material transportation in the coal mining industry as efficient and tough, Articulated Dump Truck (ADT) is used. As known Articulated Dump Truck is a variant of the offhighway truck where the cabin and the back of the dump truck including dump body can be articulated to adjust the extreme field conditions.

This study established a truck dispatching model adopting 01 decision variables to rationally allocate truck transportation in openpit mines, maximize the total loading and unloading volume of trucks, and solve the problem of the inability of the truck dispatching model to guide production in openpit mines because of nonspecific results. The model considers loading and unloading logical ...

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.

Mining trucks, also referred to as haul trucks or road trucks, are used to haul (transport) the ore or waste material from the loader to the dumpsite. In most cases, these vary from 36 tons to 315 tons. The size and cost of operating mining trucks are directly proportional to its tray capacity, while the

Both LHDs and mining trucks (figure 2) can be used in underground mines and fitted with automatic systems. However, while the former have a bucket and can therefore load the ore/minerals, the latter can be used only for transportation. In open cast mining, it is common to use larger trucks than those used in underground mines.
