Equipment selection process into three phases i.E.Type of fleet, size of equipment and calculation of required numbers, the present article focuses on different application methods in each of these phases, their advantages and shortcomings.Keywords surface mining equipment selection sizing equipment, fleet selection 1.Introduction.
Equipment selection for surface mining a review christina burt.Copper, coal and gold.There are several methods of surface mining, including openpit, stripping, dredging and mountaintop removal.This paper focuses on openpit surface mining,.Of compatibility is a complicating characteristic of surface mining equipment selection.
New technology has enabled greater productivity and safer mining in underground operations, which has also helped decrease the cost of such production methods.Cut and fill mining in this selective mining method, the void created by mining is backfilled with a mixture of waste rock or tailings with cement sometimes added to strengthen the.
Methods to select equipment for surface mines, these methods are commonly applied to the equipment selection problem in the mining.Is most effectively used in mining equipment selection to analyse the earthmoving system, some equipment selection solutions exist that use simulation models.Kannan et al.2000 recognise.
By sandstone partings was selected.For each individual mining activity all the factors influencing the selection of mining equipment are tabulated, followed by a review of possible mining methods and an economical appraisal of the various methods and equipment proposed.
Drawing and operating large mining equipment in the restricted stoping space.Therefore, considerations are required to adopt an efficient mining method that is capable of dealing with the irregular boundary of this kind of orebody, resulting in a high recovery rate while minimising the ore dilution and the preparations prior to stoping.
One of the principal costs in mine is related to purchase and application of equipment.Proper fleet selection, in a way that it secures the production needs of a mine as well as minimizes costs of production, is one of the real challenges of mine planners.As such, with the selection of suitable fleet of equipment and their application, could minimize the capital and operational costs.

Technical field.This invention relates to mining methods and equipment.Background.Longwall mining is a method of mining in which a relatively long mining face typically in the range 200 to 460 m that is created by driving a roadway at right angles between two continuous miner sections that form the sides of the longwall block, with one rib of this new roadway forming the.
Surface mining methods and equipment.Most bauxite, iron, and copper ore is mined by open pit techniques, lead and zinc ore are principally extracted by underground mining methods, and precious metals, particularly gold and most notably in the usa and australia, tend to.
Hazard identification and risk analysis involves identification of undesirable events that leads to a hazard, the analysis of hazard mechanism by which this undesirable event could occur and usually the estimation of extent, magnitude and likelihood of harmful effects.
