摘要

A method for carrying out wire bolting of a rock, in which method a hole is drilled in a rock, and a wire piece shorter than the hole is pushed into the hole. In order to simplify the insertion, the wire piece is pushed into the hole by the same wire from which the wire piece has been cut. A wire bolting device developed for effecting the method comprises a cutting device mounted on the carrier of the device between a wire feeding mechanism and a resilient guide pipe attached to a head guide. A mounting space is provided beside the cutting device for the mounting of a pushing support between the ends of the cut wire.
