FIELD: mining engineering.
SUBSTANCE: invention relates to mineral resource industry, particularly to fixation of mine openings by bolting. Arm-polymeric anchor consists of load-bearing rod, at the end of which it is threaded screw nut. Anchor is additionally outfitted by two or several ampoules with polymeric compound, divided by pistons and fixed around the load-bearing rod. Additionally ampoules with polymeric compound corresponds plain bag of length, width and thickness, depending on output of rocks stratum, in which is in prospect to implemented fixation of anchor, and on load-bearing rod there are perpendicularly installed elements for breaking of ampule film.
EFFECT: dense fixation of rod in not in one, but in several stratums of rocks, that increases load-bearing capacity of anchor.
