MOBILE MINING MACHINE AND METHOD FOR DRIVING TUNNELS, ROADWAYS AND SHAFTS, IN PARTICULAR IN HARD ROCK Russian patent published in 2016 - IPC E21C27/24 E21C25/10 

FIELD: mining.

SUBSTANCE: group of inventions relates to a mobile mining machine, in particular, for driving and advancing tunnels. Method for driving tunnels, drifts and mines with the help of the mining machine, with a movable machine base frame, with (at least) one tool drum, which comprises a bearing frame with at least one drum tool magazine, which can be rotated about a drum axis and has stripping tools, arranged on the circumference of the tool drum, with a rotary drive for the tool drum, with a boom device, with a swinging device for the tool drum with a rotating device for rotating the boom device relatively to a movable machine base, and with a rotary device for tilting of the arrow-shaped device. Boom device has a supporting arm, on which the tool drum 50 is mounted, and a separate swinging base arranged to turn relative to movable machine base, by means of Rotating device. Supporting arm and the swinging base being connected to one another by means of a system of guide bars, providing adjustment of the setting angle of the drum axis in relation to the swing axis. System of guide bars, preferably formed as a trapezoidal four-bar linkage mechanism and has the first bracket on the side of the supporting arm and the second bracket on the side of the swinging base, which are connected by means of levers.

EFFECT: technical result is ability to bring about the driving and advancing of tunnels, roadways and shafts as well in hard rock with a high extraction rate and low tool wear.
