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