MINER FOR EXCAVATION OF MINERALS AND PROCEDURE FOR THEIR EXCAVATION Russian patent published in 2009 - IPC E21C27/02 E21C31/04 

FIELD: mining.

SUBSTANCE: group of inventions refers to mining, particularly to miner for excavating beds of minerals. The miner for excavation of beds of minerals with rock inclusions, notably, of coal beds, consists of case 22 with electrical 2 and hydraulic 3 blocks arranged on the case, of control panels 4 and 5 of the hydraulic blocks and of mechanisms 7 and 8 for miner advance; said mechanisms interact with a pin bar 10 of conveyor 9. Also the miner consists of at least one handle 15 swiveling in vertical plane and assembled at the end of case 22; the handle is equipped with actuator 23 for mineral cutting; the actuator is driven to rotation by means of engine 17 and reducer 18 placed inside handle 15. Also the miner is equipped with main mechanism 24 installed between handle 15 and case 22; the main mechanism advances handle 15 onto a face at destructing of rock inclusions and it is equipped with facility 25 for maintaining the miner immobile, when actuator 23 is cutting rock inclusions.
