FIELD: mining.

SUBSTANCE: invention relates to mining, namely to mining equipment for driving and construction of vertical mine shafts. Proposed machine comprises housing with rotary base made with through opening. On the rotary base there fixed is a rock-breaking device of selective action, which is located mainly under part of the rotary base, which is not occupied with a through window. On the rotary base on the side of the through window there is a rotary bracket, on which a loading element with a breaking boom and a ladle is fixed, at that the rock destruction and loading bodies are made with possibility to develop the working face and removal of the broken rock simultaneously and separately in technologically independent zones during the whole development process. At the same time on the wall of the rotary base, which delimits the through window from the rest of the rotary base, a bin is mounted, in the lower part of which there is a device for unloading of the demolished rock stored down in the hopper.
