MINING PLANT FOR EXTRACTION OF MINERAL MATERIALS, LYING IN THE FORM OF FORMATIONS OR ARRAYS AND TUNNELING COMBINE Russian patent published in 2016 - IPC E21C27/24 E21C25/10 

FIELD: mining industry.

SUBSTANCE: invention is related to mining plant for extraction of mineral materials, lying in the form of formations or mass of the deposit containing conveyor device to make material and also containing tunneling combine. Combine production unit contains at least one pair of drums, equipped with tools for development of material and coaxially installed on rotary arm and adjusted in height relative to bed machine with the help of rotary hand. Axis of the indicated pair of drums, in fact, is parallel to direction of movement of heading machine. Tools for development of material are arranged in groups on tool supports, arranged along circumference of every drum of the above pair of drums with possibility of rotation around axes located across the axis of the above pair of drums. Rotation axes of tool supports on the first of the above pair of drums are arranged at an angle of 90°-γ relative to the axis of the first drum, and the rotation axes of tool supports on the second of the above pair of drums are arranged at an angle of 90°+γ relative to axis of the second drum.

EFFECT: technical result is high efficiency of extraction of material and reduced wear at the same time.
