CONTROLLABLE SHIELD ROOF FOR MINING OF STEEP SEAMS WITH MINED-OUT SPACE FILLING Russian patent published in 2008 - IPC E21D19/02 

Abstract RU 2332570 C1

FIELD: mining industry.

SUBSTANCE: present invention relates to mining and may be used for mining steep seams using the hydraulic method, with mined-out space filling. A controllable shield roof for mining steep seams with mined-out space filling includes hoists, jacks, a receiving device, cables, on which pipe pieces with lugs for the attachment of metallic plates are installed; a water-protection element, and "aprons". The shield roof cables are located in the centre, as well as at the roof and floor of the seam, and strengthened by jacks. Metallic plates are pivotally connected to the cables, a water-protection element and "aprons" being attached above the plates at the seam roof and floor sides.

EFFECT: efficient working of steep seams, decreased water-protection element mounting and dismantling work, reliable insulation of mined-out space.
