METHOD AND DEVICE FOR CONTROLLING CEILING AND PREPARING MASSIVE BEDS OF MINERAL RESOURCES FOR EXTRACTION BY REMOVING THEM FROM MASSIF BELOW THE CEILING Russian patent published in 2005 - IPC

FIELD: mining industry.

SUBSTANCE: method includes driving mines in front of cleaning face, processing ceiling and mineral resource by softening agents and extraction of it by cleaning combines with additional removal of mineral resource from below the ceiling. In massif below the ceiling shafts and mines are driven at maximal distance on basis of capabilities of used drilling equipment, not allowing during drilling fro processing massif below ceiling deviation from it until contact with surface by face-adjacent ceiling, supported by cleaning combine support, and distance between following driven mines is doubled, which mines are necessary for displacement of drilling equipment and equipment for feeding softening agent into wells. After finishing its pumping these wells and mines are used through connections in shafts with removing pipeline for extracting methane and degassing mineral resources. Stack of mineral resource unprocessed by softening agent has value of no more than one-two steps of extraction of coal bands along whole length of cleaning face, and the very removal of mineral resources from massif is performed in portions along whole length of mineral resource no more than 2-3 thicknesses f cutting bands of mineral resource. Device for cutting massif includes sections of mechanized support, containing base, connected to spreader posts, extending executive tool. Combine support on the side of cave-in between back posts has wedge-shaped cutting posts, hydraulically connected to back posts. Cutting posts are provided with individual means for controlling feed and draining of hydraulic liquid. Cutting posts have devices, forming in case of their spreading vibration of hydraulic liquid sent to them.

EFFECT: higher efficiency, higher personnel safety.
