FIELD: mining.
SUBSTANCE: method involves driving of mine workings of the first order at an angle of 5-7° to horizon through pillars with width equal to one bay, their further stowing with stowing mixture and its solidification, driving of entry ways of the second order with their further stowing with stowing mixture. Entry ways of the second order are driven with the height increased in relation to entry ways of the first order by 0.7-1.0 m. Cavities under roof of adjacent entry ways of the first order are filled with stowing mixture of entry ways of the second order, thus providing their stowing and contact of covering mining thickness with stowing mass.
EFFECT: increasing ore development safety.
