  1. FPC Assignment 1

  2. Go to Your Project and Fire-Up MSOPIT

  3. Go Directly to Design Strategy Pick your resource option and run

  4. Size Your Pit Reserves from the Report I can see all my ore Is sulfide I can see I have 432,517,319 tonnes ore 386,365,687 tonnes waste

  5. Setting Production Rate • Back half of room – you will mine your tonnage over 40 years • Front half of room – you will mine your tonnage over 25 years • Create and Word Document • Calculate out your annual ore and waste tonnages • Put the results in your word document • Assume even ore and waste tonnage each year • Your mill is a 1 mile drive over level once you leave the mine • Your leach is 1.5 mile at +2.5% grade uphill • Your dump is 2.5 miles at +1.5% grade uphill

  6. Climate • Right half the room • You are near Fairbanks Alaska • Left half the room • You are near Mexico City

  7. Decision Time • Determine how many days per year you can run • Write this in a word document and tell me why • Determine how many shifts per day you will run and how long the shifts will be • Write your results in a word document • Determine how many hours you will plan on • Then assume that you will only be able to utilize 93% of those hours due to pit delays • Write your results for number of hours per year.

  8. Keep on Truckin • Determine your width of road and the turn radius of your sharpest turn. • Hint – click a point hold down right mouse key and drag for distance • Look at trucks • Need absolute min 2.5 times truck width – 3 times desirable • Suppose your road is 30 meters wide (about 98 feet) • Maximum truck width about 33 feet • Check turn radius too. • Which Cat trucks are feasible to use?

  9. Consider Your Loader • Your benches are 15 meters high • Your loader must have a 15 meter dig height • Which loaders are feasible to use?

  10. Narrow Your Truck Field • Identify 3 possible trucks that might work • You may want to consider • Trucks of 250 tons or better require special haul roads • To many little trucks could be a nightmare number running around • To few of loading points will cause mill headgrade problems (think at least 3 load points) • For porphyry copper ore determine whether the trucks are weight or volume limited

  11. Look Again at Your Loaders • Assume medium dig for a hydraulic shovel, hard for a cable • What kind of fill factors can you get on your bucket or dipper. • Match your 3 trucks with loaders • Make sure your loader can get over the side of your truck • Calculate the number of passes and fill factors you will need to load your truck

  12. Get Your 3 possible Equipment Sets • Have it ready to turn in on Thursday.
