A Coal Resource Assessment for Afghanistan U.S. Department of the Interior U.S. Geological Survey by John SanFilipo background: Giral Coal Mine, 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 FY 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

“Unioned” GIS covers for calculating coal resources
Coal resource map – detail of mine areas
Resources table calculated from GIS (example is small subset of one of many tables created from slides 56 and 57) Millions of short tons of coal
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
