ORE PASS ROCK MASS DISCHARGE COMPLEX Russian patent published in 2010 - IPC E21F13/00 B65D90/54 

FIELD: mining.

SUBSTANCE: in ore pass rock mass discharge complex, its bottom part at discharge hole area has enlarged diametre with stepped fitting to the smaller diametre upper part and equipped with vertical support beams fixed along its perimetre on a internal surface. A chain gate upper ring fixed on the beams upper sides. The ore pass bottom part dimensions defined with ration. The bottom rings equipped with slides installed on it and located along its external perimetre with the same step, with possibility of their rotation at vertical axis and interaction with a vertically oriented cylindrical form case internal surface. The case fixed on fixed foundation and located with ability to mage chains with a gap. The bottom ring from its bottom side is a rim shaped with possibility to dislocate it inside a steel wire cable channel, which fixed on the rime form one side and on the drum from another side. The drum cinematically connected to the drive equipped with brake. In its initial location, at the gates opened the cable covers the rim along it total circle length. The cable branch going down from the rim located with a possibility to cover from the bottom the drifting block with a possibility to rotate along its axis. The axis equipped with sliders, which located with a possibility of their vertical guides displacement and equipped with a balance. The balance based on the foundation at its initial position. The drum top located over the rim with exceeding of the bottom ring vertical displacement at the ore pass discharge hole shut down. The drum axis horizontal displacement away from the drifting block axis selected from a rough equilibrium of a creeping on and coming off cable branches tightening resultant, for the bottom ring at the initial position and after its displacement to the top at discharged hole shut down with threaded chains. The case equipped with a vertical slot-hole with possibility to locate the cable with in it with gaps, coming of the bottom blocks rim. Slot-hole height assumed to be not smaller than the bottom ring vertical displacement movement.

EFFECT: ore pass big scale rock mass discharge complex height decrease and its simplified design.
