Acta Montanistica Slovaca Ročník 15 (2010), číslo 2, 95-101 95 Performance Measurement of Mining Equipments by Utilizing OEE Sermin Elevli1 and Birol Elevli2 Over the past century, open pit mines have steadily increased their production rate by using larger equipments which require
Since open pit mines are generally larger than underground mines there is an economy of scale associated with surface mining Large equipment with high utilization can be used in place of labor intensive underground mining methods Because of the area involved in open pit mining there is a less constricted flow of materials and mining equipment
Heavy haul trucks frequent these roads and so the grades must accommodate the braking limits and stopping distances of such vehicl The brake performance of both the 830E and 785C haul trucks have been taken into account in the decision to construct in-pit haul roads at a maximum grade of 10%

Truck dispatching is an important issue to be tackled in the Open-Pit Mining Area because of the costs of material transportation, which can represent up to 60% of operating expenditure in realistic settings The problem usually involves a truck dispatching system in which decisions on truck assignments and destinations are taken in real-time
San Diego, USA In the case of Autonomous Haulage Trucks in an open pit mine, not only is the road geometry known, but the speeds in each segment of travel are known to reasonable accuracy since there is minimal interruption in the travel cycle and other traffic is accounted for which minimizes unplanned situations to which the truck must respond
however, for large-scale open pit mining in particular, the \truck and loader" material movement practice is the preferred method of materials handling (Czaplicki, 1992; Ta et al, 2005) Throughout this paper, we consider a \loader" to be any type of high productivity excavating
Design of Surface Mine Haulage Roads – A Manual By Walter W Kaufman and James C Ault ABSTRACT This Bureau of Mines manual for design of surface mine haulage roads covers such aspects of haulage road design as road alignment (both vertical and horizontal), construction materials, cross slope, and drainage provisions
The Bingham Canyon Mine, more commonly known as Kennecott Copper Mine among locals, is an open-pit mining operation extracting a large porphyry copper deposit southwest of Salt Lake City, Utah, in the Oquirrh MountainsThe mine is the largest man-made excavation in the world and is considered to have produced more copper than any other mine in history – more than 19 million tons

open-pit mine In such operations, materials handling system is composed of loading, hauling and dumping Shovel-truck systems are most common inopen - pit mining, involving any combination of loading units and trucks This paper provides an analysis of truck-shovel loading cycle time under changing locations  
In an open pit mine operated by trucks and shovels, the trucks should be dispatched from the crusher to the shovels in such a way that the productivity of trucks and shovels in maximized while maintaining a rational production plan as well as obtaining target grades and other objectives with small variations at the entrance to the concentrator
The Evaluation of Haulage Truck Size Ef-fects on Open Pit Mining (2004), agreed “In theory, bigger is better if we can man-age the side effects,” he sa Ebrahimi, who teaches mine planning and design at Sunrise or sunset for the era of the ultra-class hauler? The bigger trucks hit the market in the upswing of a commodities super cycle .
