The average work cycle of electric mining shovel can take approximately 25 45 s depending on the machine, load, swing angle, bank conditions an d oper ator pro ciency [ 12 ].
Shoveltruck systems are most common inopen pit mining, involving any combination of loading units and trucks. This paper provides an analysis of truckshovel loading cycle time under changing locations [6] [8]. There are various factors influencing the shovel .

The loading and hauling process continues after the break and lasts the entire duration of the shift. Trucks and excavators are refueled and maintained after a mining shift in preparation for the next shift. represents a flow chart of the load and haul process.

Optimization of the loading and hauling fleet at Mamatwan open pit mine Mining Mamatwan Mine is a conventional opencast operation in that the overburden is removed to uncover the manganese orebody using a truck and shovel fleet. The orebody is then drilled and blasted (Van Antwerpen (2004.) Removal of the overburden is done in stages, where the
In mining operations, queuing models are normally observed during the hauling cycle of trucks from the loading position, in which trucks arrive at the shovels, wait for their turn in queue if there is any truck being loaded, to the dumping sites and then start a new circle. The below depicts a basic mining

#0183;#32;Truck/Shovel Haulage Systems Meredith Augusta May Abstract Surface mining is the most common mining method worldwide, and open pit mining accounts for more than 60% of all surface output. Haulage costs account for as much as 60% of the total operating cost for these types of mines, so it is desirable to maintain an efficient haulage system.
Performance Measurement of Mining Equipments by Utilizing surface mines. In a surface mining operation, materials handling system is composed of loading, hauling and dumping. Shoveltruck systems are most common in open pit mining. Shoveltruck refers to a loadhauldump mining system, involving any combination of loading units and trucks.
#0183;#32;face height and adequate infrastructure, the electric rope shovel (ERS) can deliver the lowest cost per ton. The mine life must be long enough to support the investment in a machine with a long life and the option to rebuild. In addition, the loading process must be supported by a rightsized, efficient hauling fleet. Hydraulic Mining Shovels.
