POWERED SUPPORT FOR INCLINED FORMATIONS Russian patent published in 2015 - IPC E21D23/00 

FIELD: mining.

SUBSTANCE: invention proposes a powered support for inclined heavy formations, which includes sections, each of which includes a bar, a shoe, a pneumatic post and a goaf enclosure, as well as a capsule of a hardware compartment and a hauling mechanism. The pneumatic post is located on a support yielding arch consisting of hinged sectors spring-loaded with plate springs and softly supported from the shoe through air shock absorbers. Besides, the hauling mechanism consists of two manipulators supported from bed soil and an ultrasonic generator with a waveguide providing smooth sliding of the shoe along bed soil at hauling of the support.

EFFECT: proposed support provides further improvement of serviceability of the support on steep dip due to improvement of the design; improving stability; reducing energy consumption at hauling of the support and ultrahigh flexibility.
