Electric mining haul trucks are one of the most challenging applications of power electronics in automotive systems. This paper presents some advances in veryhighpower trucks used in copper ...
Mine production automation system is a coal mine focus the system aspects involved mainly includes: the fully mechanized coal face control system the underground main opbelt control system, the main shaft hoisting control systems, ground coal washing system, these systems constitute a coal mine main production process, coal flow. One of the main
truck fuel consumption in Australia's surface coal mine. They also looked at GHGs and costs of haul truck fuel consumption. Rodovalho et al. [20] have created a method to identify and analyze the variables related to the hauling truck fuel consumption in openpit mines. In this research work, the mathematical modeling tools and
Miners, mine operators, and contractors have important roles to play in mine safety. Mine safety can be substantially improved by preventing accidents that involve powered haulage equipment. Accidents involving powered haulage equipment have historically accounted for a large number of the fatalities and serious injuries in mining.
The truck dispatching problem in openpit mines is formulated into an integer programming problem in order to optimally determine the trip numbers of trucks from a shovel (dump site) to a dump ...
A semicontinuous process system consisting of a singlebucket excavator, truck, crushing station, and belt conveyor is the main coal mining process system of a largescale hard coal openpit mine ...
LHDmachines are used to load the trucks at the loading bay as shown in Figure 2. When there is no truck to loadLHDs haul the material and, it on a stockpile. Loading time per pass dump includes bucket travelling time when empty, digging time, bucket travelling time when loaded, and loading
Most notably these include highwall mining machines, load haul dump vehicles (LHDs), rock drills, and haulage trucks. ... Pursuit of accurate navigation and control of continuous mining machines for coal mining, Proc. 4th Int. Symp. Mine Mech. Autom. (Brisbane 1997) pp. ... Autonomous mine truck, Mining Mag. 175(5), 287288 (1996)
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.
Fortescue Metals Group (FMG) and BHP are two of the biggest customers of Caterpillar's autonomous haulage solutions. FMG's Solomon iron ore mine is Caterpillar's flagship operation for its autonomous solutions. The mine site is being developed into a fully autonomous operation. FMG also completed the conversion of the mining truck fleet at the Chichester Hub iron ore operation in Pilbara ...
The first doublepower transmission mining truck for use in an underground mine was designed in China for a full load of 35 t, a speed of 25 km·h −1, and a maximum climbing slope of %, as shown in Fig. 14. In addition to its unmanned driving function, the truck is capable of vehicle lanespace detection and intelligent auxiliary driving ...
Trajectory planning for a heavyduty mining truck near the loading/dumping sites of an openpit mine is difficult. As opposed to trajectory planning for a smallsized passenger car in a parking ...
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.
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 ...
Improve execution of their plans in every shift. Reduce hang and queue time. Maintain and update a realtime digital twin of your mine equipment, locations and haulage roads with DISPATCH. This fleet management system continuously optimizes your routes and utilizes automated communication to help keep your truck operators informed and connected.
bunkers and from the bunkers the coal is transported into Washery by the Trucks after weighing on 60T Lorry weigh bridge. Transportation of Coal by Trucks is not under this scope. After washing and other arrangements the grade Coal converted to G9 G12 washed G9 grade coal, after weighment on 60T Lorry weighbridge,
Autoloading without modification of the truck. The NALON N8 is a system for the automated loading and unloading of trucks and containers. The system is va lid for any truck with no need for modifications, and has a capacity of 150 pallets per hour. The NALON N8 can work on multiple loading docks, thereby increasing productivity.
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.
AutoMine®. The AutoMine® product group offers autonomous and remotely operated mobile equipment. It allows operators to simultaneously control and monitor multiple underground and surface machine operations in the comfort and safety of a remote control room. With AutoMine®, customers can scale up automation at their own pace.
Construction of intelligent coal mine knowledge map. Through the establishment of information entities, the mapping from the physical space to the digital space is realized. This mapping includes not only physical entities (, coal mining machines, hydraulic supports, and tunneling machines), but also time entities (, roof pressure, gas overruns, equipment failures) and functional ...
Transport activities in openpit mines contribute to a large portion of total energy consumption. Most truck scheduling studies still take a traditional approach to autonomous mining trucks, which does not fully exploit the strengths of the autonomous trucks that can perform more accurate speed control compared to conventional manned trucks. In this paper, a mixedinteger programming model is ...
