OBJECTIVES OBJECTIVES

  • Provide assessment how much coal is available for mining
  • Characterize quality of coal for those unique properties to

utilize it in an efficient and environmentally sound manner;

  • Characterize current use of coal;
  • Characterize production and use of Coal Combustion

Products;

  • Characterize limestones and dolomites for Flue Gas

Desulphurization

  • Provide basis for potential uses of Indiana coals (CBM,

CO2 sequestration, non-traditional uses of CCP)

CONTENTS CONTENTS

  • 74 pages of text, 102 figures and 67 tables
  • Resource evaluation for all major coal beds (Danville, Springfield, Seelyville

from previous availability work at IGS, Hymera, Houchin Creek, Survant and Colchester – new evaluations, Lower and Upper Blocks and Buffaloville – extents and area available for mining). More than 50 maps of depth, thickness, areas available for underground and surface mining have been generated.

  • Physical and chemical properties (sulfur, ash, heating value – summaries and

maps for major coal beds, ash characteristics, summaries of 35 trace elements – Hg, Se, As, and Cl discussed in more detail).

  • Utilization (coking properties, SR 64 by Valia and Mastalerz, CBM, CO2

sequestration – DOE-sponsored projects)

  • Coal Combustion Products from Indiana coals;
  • Limestones and dolomites for Flue Gas Desulphurization – recent IDOC-

funded project to N. Shaffer; and

  • Summary of the unique properties of Indiana coals.

This document uses all the information that was available to us, both old and the most recent,

Availability of Coal Reserves in Availability of Coal Reserves in Indiana Indiana

  • Indiana had approximately 59.5 billion short tons
  • f original coal resources
  • Available for mining is 17.5 billion (~30%)
  • Available for surface: ~ 2 billion

for underground ~ 16 billion

  • Coal produced in Indiana so far: 2,124,417,385

tons (2 billion)

slide-8
SLIDE 8

Rate of Recovery Rate of Recovery

  • Continue to mine ~30 million tons per

year, all that is available (17 billion tons) is mined in approximately 500 years.

  • However, only 2.1 billion is available for

surface m. – 70 year supply if surface mined only

  • Not more than 20% Indiana production

comes from underground mines.

ratio, etc. – Brazil Formation coals have superior coking properties

  • Pulverized coal injection (PCI) – good coals are

those that have high combustibility and replace more coke – high replacement ratio (RR).

  • Significant proportion of Indiana coals have high

SUMMARY: Availability SUMMARY: Availability

Coal availability studies shows:

17-18 billion short tons of coal are available for mining (surface and underground) in Indiana. At current production rate, this reserve would last for more than 500 years.

But this can only be accomplished by a significant increase in the percentage produced by underground mining. Production using current practices (80% surface - 20% underground) will last only 100 years.

Indiana coals, being part of the Illinois Basin, have many common characteristics with the coals of Illinois and western Kentucky.

Similar coalification level; high volatile bituminous rank dictates such properties as calorific value, moisture, carbon content, etc. High volatile bituminous rank: very suitable for combustion, but also useful for gasification

  • r liquefaction because of their reactivity.

SUMMARY: SUMMARY: Basinwide Basinwide Characteristics Characteristics

slide-49
SLIDE 49

SUMMARY: Heating Value

Indiana coals (and those of the entire Illinois Basin) have good heating value

Better than most Western coals but lower than Appalachian coals. Compared to western coals, we need to burn less Indiana coal to get the same amount of energy.

SUMMARY: Heating Value SUMMARY: Heating Value

slide-50
SLIDE 50

Most of Indiana coal is high in sulfur

Significant portions of the Danville and the Brazil Fm. coals are low-sulfur compliance coals. Illinois and western Kentucky do not have this low sulfur resource. Availability of good quality limestones (for FGD) close to our power plants helps utilize high sulfur coals.
