FIELD: mining.
SUBSTANCE: claimed process comprises the delineation of mining bord by development working and mining of bord stores by bords with interbord yielding pillars being left. Prior to mining of every board gateway is worked from development working area. Boards are mined ply-by-ply by mining combine from the gateway with drawing of sylvinite to the surface using the halite ply as the filling material at adjacent worked bord. The boards are worked in forward run starting from the mid ply. Then, the bord top ply worked in reverse run. Now, the bord bottom ply is mined in forward run. Combine drum diameter should not exceed 0.5 m where m is the ply minimum depth, m.
EFFECT: higher efficiency of board working.
