TRAVELLING BULKHEAD FOR ARRANGEMENT OF FILLING MASS IN UNDERGROUND MINE OPENINGS Russian patent published in 2009 - IPC E21F15/02 

FIELD: mining.

SUBSTANCE: invention is related to the field of mining, namely, to travelling bulkheads for arrangement of filling mass in underground mine openings. It includes metal pressure shield, which consists of separate elements fixed to each other by means of bolts, soft shells, equipped with nozzles for supply and exhaust of compressed air, pipes for drainage with filters and pipes for sampling with plug. Metal pressure shield is arranged in the form of right-angled parallelepiped, which is made of four triangular fixed prisms, bases of which have the shape of isosceles right-angled triangle. Height of triangular prisms is accepted as higher than distance between roof of filled opening and metal pressure shield, in which door opening with door is installed, and door opens in direction of filling mass location. On upper and lateral sides of metal shield, there are soft shells arranged, height of which, when completely filled with compressed air, exceeds distance between metal pressure shield and contour of opening section. On the lower side metal pressure shield is equipped with rubberised apron on the side of filling mass.

EFFECT: invention makes it possible to increase efficiency and reliability of filling mass control in filling of lengthy mine openings and layer excavation of mineral.
