3 BukitAsam THE PROJECT Exploration and Feasibility Study of deep seated coal mining development at Air Laya and surrounding area in Tanjung Enim.

4 BukitAsam BACKGROUND & OBJECTIVE Background : Air Laya Open Pit Mineable Reserves for export quality are limited (105 million ton with Geological Reserves 256 million ton) Potential of High Wall mining and and U/G Mining of deep seated coal in Air Laya to increase mining recovery Objective : To conduct Coal Reserves Exploration and to prepare a Pre Feasibility Study of High Wall Mining & U/G Mining in Air Laya mine to maintain and increase PTBA s coal export (especially to Japan).
