STRENGTHENING METHOD OF HARDENING FILLING MASS Russian patent published in 2017 - IPC C04B28/00 E02D3/12 C04B111/34 

FIELD: mining.

SUBSTANCE: invention relates to mining industry and can be used in development of mineral deposits with stowing mined space. Method of hardening of filling mass, which involves placing in formed array of reinforcing elements simultaneously with hardening mixture used reinforcing elements are modified basalt microfibre (MBM) in amount of 7.1 % of binding substance weight. Microfiber contains, wt% basalt wool with organic impregnation – 99.3–99.6, carbon nano structures of fullerene type – 0.00001–0.01, water – rest.

EFFECT: technical result is provision of safe conditions of mining operations at increase of strength of filling for tension.
