  • Selection of mining method QueensMineDesignWiki

    The various business and technical considerations influencing choice of mining method should be discussed, and linkages with topics described in other chapters should be made to emphasize value creation through consideration of the entire mining system as opposed to single components of the design The understanding of value creation and where value is lost in our mine design and09/03/2018· Compared to other mining methods, roomandpillar mining is a lowcost method with a low recovery rate (since some ore is left behind in pillars) Yet, the method causes very little dilution as the contact between ore and waste is limited due to the waste being on top and ore being at the bottom Direct operating costs for roomandpillar method range from $5$20/tonne Some variations of theTypes of Mining Methods | Sell Side HandbookThe choice of mining method depends on man y fact ors, including: 1) Shape of the orebody (ie, t abular , cylindrical, spheric al) 2) Orienta tion of the orebody (ie, subhorizontal, sub(PDF) Mining Methods ResearchGate

  • Mining method selection by multiple criteria decision

    Mining method selection is one of the most critical and problematic activities of mining engineering The ultimate goals of mining method selection are to maximize company profit, maximize recovery of the mineral resources and provide a safe environment for the miners by selecting the method with the least problems among the feasible alternatives Selection of an appropriate mining method is aUnderground mining methods are the focus of this article The selection of a mining method for an ore deposit is based on many factors that are driven by the economics and profitability of the mine for a company These include the following: Ore grade and recovery; Cost of infrastructure; Ore extraction ; Labour and machine costs; Underground support costs; Geotechnical factors; Retrieved fromFactors influencing mining method selectionFinal choice of mining method will reflect both the engineering properties of the orebody and its setting, and the engineering attributes of the various methods such as mining scale, production rate, selectivity, personal ingress requirements and extraction flexibilityFor the large, often low grade orebodies, selecting the proper mining method is difficult: block caving is generally12 Mining methods and method selection

  • What are the main methods of mining? | American

    There are four main mining methods: underground, open surface (pit), placer, and insitu mining Underground mines are more expensive and are often used to reach deeper deposits Surface mines are typically used for more shallow and less valuable deposits Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environmentsUnderground mining methods are the focus of this article The selection of a mining method for an ore deposit is based on many factors that are driven by the economics and profitability of the mine for a company These include the following: Ore grade and recovery; Cost of infrastructure; Ore extraction ; Labour and machine costs; Underground support costs; Geotechnical factors; Retrieved fromFactors influencing mining method selection01/03/2009· Once selected a mining method, as it is nearly impossible to change it owing to the rising costs and mining losses, it is very important to reanalyze the decision made before carrying it out The method that the decision makers generally use for this aim is the sensitivity analysis on the final decision 2 Literature review 21 Studies on mining method selection The problem of undergroundUnderground mining method selection by decision

    The UBC mining method selection is a modification of the Nicolas methodology that better represents typical Canadian mining design practices The main weaknesses of these approaches are in the fact that the importance of each selection criteria has not been considered An uptodate approach considers mining method selection as a multicriteria decisionmaking (MCDM) problem with a finiteThe choice of mining method depends on many factors, including: Shape of the ore body: tabular, cylindrical, spherical Orientation of the ore body: subhorizontal, subvertical Continuity of the ore body Oregrade: highgrade, lowgrade Distribution of orebearing minerals within the orebody: massive or disseminated (with a cutoff grade) Depth to the ore body Strength of the ore bodyi) Mechanical excavation methods; such as Openpit andThe selection of underground mining methods is primarily based on the geological/spatial setting of the deposit Candidate methods can therefore be chosen and ranked based on estimated operational/capital costs, production rates, availability of labors and materials/equipments, and environmental considerations The method offering the most reasonable and optimized combination of safe tyUnderground Mining Methods and Equipment
