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.
