METHOD OF SHRINKAGE RELATIVE DEFORMATION MINIMIZATION OF HARDENING FILLING MASS Russian patent published in 2017 - IPC E21F15/00 C04B28/00 C04B111/34 

FIELD: mining.

SUBSTANCE: invention relates to mining industry and can be used in development of mineral deposits with hardening stowing of mined-out space. Method of shrinkage relative deformation minimization of hardening filling mass is proposed to achieve the technical result, including arrangement of reinforcing elements simultaneously with hardening mixture in the mass, at that, to ensure uniformity, said mixture is required to be mixed for 25 minutes min, and chrysotile asbestos – chrysotile in an amount of 10 % of the binder weight are used as reinforcing elements.

EFFECT: technical result of the present invention consists in stability improvement of the artificial roof, limitation of underground mining works negative influence on the environment, maintaining integrity of the ground surface and protecting it against sedimentation.
