FIELD: mining industry. SUBSTANCE: this is intended for use in cutter-loader extraction of ore from contiguous flat seams. Ore recovery is carried out by coaxially located alternating single-entry chambers and multiple-entry chambers. Left between entries of chambers are pliable pillars which are located in seams noncoaxially relative to each other. Being formed above multiple-entry chambers of upper seam is arch of relieved rock. Central part of each multiple-entry chamber in upper seam is being worked after driving through leading single-entry chamber. Application of aforesaid method reduces cost of ore extraction due to increased productivity without impairing safety of mining operations. EFFECT: higher efficiency. 1 dwg
