It defines a box cut as the initial cut that reaches the ore body and facilitates bench development. In place of the dragline, a shovel can be used to remove overburden from the second cut thus eliminating the need to create an upslope bench. Block-cut mining can be applied to either area or contour mining FigEnd-cut mining method. If the overburden is thick a rehandle method is necessary Surface Mining: Deposits amenable to surface mining ; Box Cut ; Objectives types parameters and methods, production benches Objectives,formation and benches parameters,Unit Operation and associated equipments,Classification of surface mining systems. Assessment based on site observations, structural/kinematicanalysis (DIPS) and empirical ground support box cut. Peak gold mine (NSW) The document discusses the opening of surface mining deposits through a box cut. Upon reaching the economic limit of mining, dozers push the spoil uphill to cover the highwall before revegetation commences. FigSide-cut mining method. Box cuts can be internal, within the mineralized of box cut and portal design,including appraisal of empirical and structural analysis methodologies applied. Module II Peak gold mine (NSW)Geotechnical assessment and ground support design recommendations for boxcut, side batters and portal face. Mt Wright gold project (QLD)Review of box cut and portal design, including appraisal of empirical and structural analysis methodologies applied. A box cut is the initial excavation that provides access to the deposit and space for developing Traditional surface mining methods fall into two broad categories based on locale: I) Mechanical excavation methods { such as: Open-pit (or Open-cut or Open-cast) Mine planning: A case study of cut-and-fill method The critical optimization criteria of mine planning are: sus-tainable ore flow of assigned quality, mining safety, efficient utilization AEISG Code of Good Practice, “Blast Guarding in an Open Cut Mining Environment”. Note: The potential for undesired blasting outcomes at the time of firing needs to be Box Cut & BenchFree download as Word Doc.doc), PDF File.pdf), Text File.txt) or read online for free. End cut and the overburden spoil must be dumped at a greater distance from the edge of the box cut. The document discusses box cuts and the development of benches in surface mining. The extra reach needed is gained by using a dragline swing angle of up to °.
