FIELD: mining.
SUBSTANCE: method refers to mining at development of bedded deposits with long pillars along strike by upward mining with destruction of rocks of immediate roof. Method of development of bedded deposits consists in opening a mine field to a lower horizon with main, auxiliary and ventilation inclined bores, in preparing by means of running floor entries to boundaries of the mine field and in developing floors with upward mining. While preparing a lower floor rock produced at drive working is stowed in under-entry packs. After upper floors have been developed rock of drive workings is stowed in extracted entries of developed underlying floor and in opening inclined entries - in the main, auxiliary and ventilation bores, thereof simultaneously with development of stock there is performed a complete liquidation of developed space.
EFFECT: ensures operation of ecologically clean enterprises and increases efficiency of mineral extraction process.
