6. Split Projects Surface Miners – open pit copper W1 - Review Initial Data –Research product prices W2 – Read in data files start model –Identify local labor and transport routes Underground Miners – underground coal W1 – Review initial data –Research product prices W2 – Read in data files start model –Identify local labor and transport routes

7. Projects Schedule (W3) Build Ore Body Model –Identify potential reserves and cut-off (W4) Run Ultimate Pit –Identify likely minable reserves (W5) Run Stage Pits (W3) Build Model –Identify minable seams and areas –Propose methods (W4) Draft Mine Openings and Panels –Identify likely minable reserves (W5) Lay Out Draft Sequence

9. Divide Class By Interest Set Up Time –Monday – Wednesday – Thursday –Tuesday- Wednesday - Friday

10. Overview of Coal Project Starting Data consists of 80 holes drilled of 5 lines spaced ½ mile apart and drilled on ¼ mile centers Have a surface property map May use MineSight or Carlson –Mining Classes will drop Thurs / Fri / Sat for day long Carlson Training Srs have top priority Largely on own –I will be trying to do MineSight notes for project

11. Overview of Area Area may have minable reserves of #7 #6 #5 and #3 coal #7 and #6 are high sulfur steam coal –Geologists some consistency with seam elevation on #7 –#6 coal was very continuous and made a good marker seam #5 is Mid/Low Sulfur steam coal but has gray shale roof and likely channels #3 is a low grade Met coal but appears to have some significant channels and splits A sissor fault may be present

12. Rock Mechanics Considerations #7, #6, #5 coals have soft clay floors –#7 has 700 psi –#6 has 600 psi –#5 has 500 psi –Two feet thick in all cases #3 has solid rock floor #7 and #3 have massive Limestone roof #6 has a fairly uniform black shale roof #5 has a gray shale roof in many areas –It degrades over time –Falls apart when exposed to moisture (a shaft bottom consideration) –When it thins to less than about 2.4 feet it tends to fall a lot and create severe operations problems

13. More Rock Mechanics Considerations Coal Strength is 2400 psi Horizontal Stress Fields –Primary Stress is 20 degrees north of east at 1100 psi –Secondary Stress is 600 psi at 90 degrees Vertical Stress increases with depth according to an average overburden of about 150 lbs/ft^3

14. Location Coal property is near Carmi, Illinois Your initial data set is 80 drill holes and a surface property map

15. Things to Start Right Now Begin researching coal prices and trends to set expected sale price of coal –USDOE probably best source (found back to 1985) –Need to adjust prices to constant 2009 dollars Need to pick up data and start making input decisions to get the data into a model –Right now Excel files If you go with Carlson probably committing to the Thurs / Fri / Sat Seminar
