Abstract
The authors offer the optional versions of mining methods and technological schemes for mining at Udachnaya pipe reserves under the opencast bottom. The rational chamber-and-pillar method has been substantiated, considering the complicated mining-geological and geomechanical condition at the deposit. The economical feasibility of the proposed underground mining variants has been evaluated.
