Essay About Pc3000 Specifications And Mining Operation

Mining Equipment Selection
IntroductionRemovement of waste rocks is one of the key issues in mining operation process.As the Marsupial Mining Corporation describes, an efficient and cost-effective method is needed for them to carry out a successful completion of exploiting Numbat deposit via an open pit operation.In order to ensure it, the most appropriate fleet are required to be chosen by estimating the costs involved which including Expected cost of loading in $/year and $/tonne as well as Expected cost of hauling in $/year and $/tonne. Also, it has to meet the production target for waste removal. Due to a corporate arrangement, the loader(s) can only select a Komatsu “Face Shovel” model, while the truck(s) can only select a Caterpillar model. To clarify the reason of choice for loaded(s) and truck(s), the calculation results will be provided using the parameters in given data sheet and appendix.1.Calculation and Explanation 1.1Calculation of shovel and truck productivityTo calculate the shovel and truck productivity, the values of their capacity are needed.it can be found in relevant materials and shown above:ParameterValueJustificationPC3000 bucket capacity15[pic 1]PC3000 specifications (see Appendix)PC3000 cycle time40[pic 2]PC3000 specifications (see Appendix)PC4000 bucket capacity22[pic 3]PC4000 specifications (see Appendix)PC4000 cycle time43[pic 4]PC4000 specifications (see Appendix)PC5500 bucket capacity28[pic 5]PC5500 specifications (see Appendix)PC5500 cycle time44[pic 6]PC5500 specifications (see Appendix)PC8000 bucket capacity42[pic 7]PC8000 specifications (see Appendix)PC8000 cycle time46[pic 8]PC8000 specifications (see Appendix)777G truck capacity90.8t777G specifications (see Appendix)777G truck unload time41s777G specifications (see Appendix)785D truck capacity144t785D specifications (see Appendix)785D truck unload time63.2s785D specifications (see Appendix)789C truck capacity177t789C specifications (see Appendix)789C truck unload time51.8s789C specifications (see Appendix)789D truck capacity181t789D specifications (see Appendix)789D truck unload time51.8s789D specifications (see Appendix)793D truck capacity218t793D specifications (see Appendix)793D truck unload time57.02s793D specifications (see Appendix)795F AC truck capacity313t795F AC specifications (see Appendix)795F AC truck unload time66s795F AC specifications (see Appendix)797F truck capacity363t797F specifications (see Appendix)797F truck unload time44s797F specifications (see Appendix)Table 1.
