A method for development of inclined and steep mineral beds with chamber systems includes separation of blocks to chamber stocks, inter-chamber pillars and ceiling, with penetration of preparatory - cutting workings, breakage and discharge of chamber rock stocks and stock of inter-chamber pillar, breakage and discharge of ceiling stock in turn. After extraction of stock of cleaning block one breaks at side of suspended rock part of ceiling stock, with discharge and filling cavity of chamber with laying rocks with formation of compensation trench under part of ceiling left due to natural inclination of overlying rocks broken to chamber. After that one breaks stock of part of ceiling left and discharges those through catching delivery workings, those are preliminarily penetrated in rocks of laying side.
