FIELD: mining.
SUBSTANCE: invention relates to mining industry and can be used at underground development of ore deposits by the processing chamber systems. Method of the mined-out space filling involves filling the mined-out space of the chamber by hardening mixture and a controlled projectile reset of the rock filling. Hardening array is created at the boundary of the coupled chamber solid ore and it is about 30 % of total volume of formed filling mass.
EFFECT: invention ensures to increase efficiency of filling and to exclude the presence of people and equipment in the filled chamber.
