In the earlier approved Scheme of Mining, it was proposed that both the  Raikela quarry in the South Eastern part and the Tantra quarry in the North–East & Western part be developed simultaneously. The area would be developed from the bottom to the top towards the right side of the hill. The generated waste was proposed to be disposed off in the existing dump located in south eastern part, which has already been stabilized.

The earlier Scheme of Mining was approved by the Other Than Fully Mechanized Method. This Scheme of Mining has been prepared as Fully Mechanized Method (FM).
