Abstract RU 2593665 C1

FIELD: mining.

SUBSTANCE: invention relates to mining industry and, in particular, to anchor support, and can be used for attachment of mine workings circuits. Composite mine anchor includes a load-carrying rod from composite material on the basis of fibers and polymer binder. Anchor is solid in cross section and has a head part with screw groove and a shank. Shank has thread and nut. Polymer binder of the composite material includes grains of ferromagnetic powder. Said grains allow removing parts of the load-carrying rod destroyed during coal production with the help of magnetic catchers.
