Optimal Mining Solutions provides expert truck and shovel haulage analysis work in Deswik and OptiHaul. Our consultants have completed haulage models for some of the world''s biggest mining companies and contractors. Our consultants can provide expert analysis of haulage options, fleet configurations and full costing of truck and shovel operations.
idle time of the shovel and the cost of providing extra trucks. The solution yields the optimum number of trucks of any given capacity that can be assigned to a shovel. For an operation involving single shovel and N trucks, the total hourly cost is C1 + C2 N, where C1 is the cost per unit time of shovel and C2 is the cost per unit time of a
in surface mining is by truck and shovel combination. This operation is one of the key factor to reduce the cost of mineral production. This paper presents a complete methodology that can be used to determine the number of trucks required per shovel during striping and the extraction of minerals for Surface mining. The methodology is
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. The most important factor in every operation is profitability.

7/13/2014· When mining company gets the lease of a mineral deposit, the difficult is then how to mine and process that deposit the optimum way. The main problem facing managers or engineers who must select on equipment selection, mine plant site and long range scheduling is how one can optimize a property not only in terms of efficiency but also as to project duration.
