FIELD: mining.
SUBSTANCE: proposed method comprises erection of framework and filling it with solid stowing material. Note here that said framework in chamber mined-out space is made of used tires. Said tires are laid in piles from soil to course roof, interconnected and filled with rock. Then, sealing coat is laid on framework over contact with roof to feed solid solution via hole in said coat. After cementation of said solution, said chamber is isolated from adjacent courses by webs and filled with hydraulic fill.
EFFECT: higher efficiency, lower costs owing to the use of used large truck tires.
