Summary:

Asam- Asam Coal consists of six major seams which are seam until seam G. The thickness of their coal seams varies from 2-25 m with strike of N70°E and dip around 25°-35°. Asam-asam coal mine has approximately 52 million ton reserve of low rank coal at a relatively low stripping ratio which is around 4.67.
