FIELD: mining.
SUBSTANCE: invention relates to mining and can be used in development of mineral deposits with backfilling of mined space. Disclosed is a method of hardening a filling mass, which includes placing reinforcing material in the formed mass simultaneously with the hardening mixture. Reinforcing material used is rubber powder in amount of 1% of the mass of the hardening mixture. Besides, reinforcing material additionally contains one of types of fibrous material in amount of 3% of weight of binder: modified basalt microfiber or chrysotile asbestos — chrysotile.
EFFECT: increasing ultimate strength of filling mass at compression.
