background: Giral Coalbackground: Giral CoalMine, Rajasthan, IndiaMine, Rajasthan, India
Progress to date?
• 5 mines in two coal fields visited Mar 04• 7 samples of good provenance collected -
analyses in progress• 5 samples of good provenance provided by
private sector - analysis nearly done• 2 samples of dubious provenance• Geospatial in progress (ASTER, maps)
What’s next?
• Coal and geospatial travel Nov 04• Emphasis on additional samples, mine
evaluation, recon geology, literature archive
• Revisit Pol-e-Khomri with Khair• Visit 2-4 new localities• Scan Russian literature at AGS
Remaining FY05
• 3 - 4 additional trips 05 (same tasks)
• YR1 Products:• Bibliography • Archived Russian Reports• Field investigations• Coal Sector snapshot (Khair)• Coal quality database• Preliminary GIS• Preliminary assessment
COAL RESOURCE ASSESSMENT
Assess the quality and quantity of the coal resource on the local, regional , and national level.
NOT A FLUID – DOES NOT MIGRATE
Different than ore fluids or petroleum
ASSESSMENT PROCESS IS NOT PROBABALISTIC

COAL RESOURCE ASSESSMENT
• Most of the interpretive effort goes into the first step (intercept map)
• Volumetrics are relatively straightforward but tedious
• Not even close to the first step for Afghanistan
• What we need is geology
