Equipment Selection for Surface Mining: A Review
Key words: Equipment Selection, Surface Mining, ShovelTruck Productivity, Mining Method Selection, MultiCommodity Network Flow Introduction The general Equipment Selection Problem (ESP) is to choose a collection of compatible, but not necessarily homogeneous, items of equipment to perform a speci ed task In many applications, the task is to move a volume of material from a set of In open pit mining, equipment selection is made according to many factors related to the ore and mining conditions These factors can be qualitative and quantitative in nature The main purpose of equipment selection is to choose the Estimation of Open Cut Mining Recovery and Mining Estimation of Open Cut Mining Recovery and Mining Dilution By Kent Bannister, ARMIT, FAusIMM factors of equipment selection a mineequipment costs, tires, complexity, matching factorsystem approach of machines, loss of production, maintenance, infrastructure and haul roads, dilution and selectivity, flexibility and versatility, possibility of selected extraction, reflectivity and applicability, environmentalMethods for Equipments Selection in Surface Mining; review

Factors Affecting Selection of Construction Equipment
Factors specific to companies: The selection of Construction Equipment also depend on the need of the company If the company has a lot of projects in hand for the coming few months or even years, then it definitely makes sense for it to invest in the heavy CE However, if there is a oneoff job or a short term job that needs to be completed, then the company might opt for renting the other factors Figure 2 shows a comparison of the annual produ ction rates and producti vities of US coal mines Surface mines have very few limitations on the operation of large machines with high capacity, whereas underground operations are considerably restricted by narrow working spaces and rock conditions Moreover, less commuting time is required at a surface mine, whereas a much longer Surface Mining Methods and EquipmentPdf Factors Of Equipment Selection A Mine cient mining equipmentirst, the overlying soil and rock layers overburden are removedhe coal is then fractured with explosives or machines, and loaded onto vehicles for haulage from the mine siteinally, the disturbed land must be fully reclaimedrincipal considerations in the selection of surface mining and reclamation techniquesPdf Factors Of Equipment Selection A Mine

the cost of production, is one of the main challenges of mine planners The equipment selection process can be classified into three phases ie type of fleet, size of equipment, and calculation of required numbers This study focuses on the proper equipment selection that optimizes production efficiency, and meets the desired output from the available workingtime which can also be referred The limited aspects chosen for evaluation in equipment selection can be applied to different design options, or simply different brand names of equipment Simple weighted scoring can potentially identify ideal equipment, and a LCCA can validate or reevaluate that potential Choose a realistic discount rate, relative to the owner’s approximate return on investment or cost of money 14 aspects to consider in equipment selection ConsultingWe all realize that the choice of drilling equipment is the most important decision and will have a major impact of your drilling performance While the type of ground is an important factor, other factors are important to consider when drilling underground Our technical crew can supply other helpful hints for underground drilling such as: always try to use a used core bit to start when 5 Factors to Consider when Choosing Underground Drilling

Mining method selection by multiple criteria decision
Mining method selection by multiple criteria decision making tools Economic factors such as: capital cost, operating cost, mineable ore tons, orebody grades and mineral value Technical factors such as: mine recovery, flexibility of methods, machinery and mining rate Productivity factors such as annual productivity, equipment, efficiency and environmental considerations Each of these Advance ventilation involves the consideration of two principal factors: (1) the total volume flow rate of air required by the mine, and its satisfactory and economic distribution, and (2) the pressure required by the mine fan(s) A well designed ventilation system should be 167MINE VENTILATION SYSTEMSConversely, secondary dilution is the dilution that occurs beyond the planned stope dimensions Secondary dilution is caused by a number of factors which include sloughing, drilling and blasting, ground conditions, planar discontinuities, mining method, equipment, and work practicesDilution and ore recovery QueensMineDesignWiki
