FIELD: mining.
SUBSTANCE: method involves arrangement of reinforcing elements made in the form of mesh in filling chamber at the boundary with rock ore to be developed. Reinforcing elements are arranged at distance of 0.05b from each other, where b - chamber width. After installation of reinforcing elements the worked out space is filled with filling mass of various strength. Lower, central and upper part of chamber is filled at 1/10 of its height with curing mixture, and space between them with hydraulic fluid from fine material without binding agent.
EFFECT: reducing the costs; improving manufacturing capabilities.
