FIELD: mining.
SUBSTANCE: method to develop potassium beds includes a continuous development system, plow or combine mining, conveyor transportation, filling of developed space. Developed space is fenced off the bottom hole with a powered support, and backfilling material is used to completely fill the developed space, while initially developed space is filled with backfilling material with filling extent of 0.8-0.9, at the same time distance from powered support to face does not exceed 10-12 m, and then space behind partition, which remained unfilled, is backfilled to roof of withdrawn bed. Filling of bed roof is carried out with mechanical method with the help of pneumatic filling complex. Production complex operation in face is controlled automatically.
EFFECT: improved completeness of potassium ores extraction with preservation of continuity of water protection thickness, efficiency and safety of production works performance.
