BOTTOM OF THE BLOCK WITH ORE VIBRO OUTLET Russian patent published in 2018 - IPC E21C41/16 

FIELD: mining.

SUBSTANCE: bottom includes a hauling, ventilating, trenching and loading-and-delivering chambers with chambers of the operator of development. The end of the loading and delivery output is taken out under the trench and their conjugation is formed in the form of an upwardly expanding receiving chamber. Ventilation production is carried out in parallel with a pulling chamber near the end of the operator's chambers above their roof. Ventilation production is supplied with the loading and delivery through the vent wells, which provide the necessary supply of fresh air due to general mine depression. The overlap of the ventilation wells regulates the consumption of fresh air in separate sections and, in general, for the mine workings.

EFFECT: improvement of conditions, improving security and productivity in bottom blocks with ore vibro-outlet, ore extraction cost reduction can be achieved by increasing the height of the visor, the rational arrangement of ventilation and it's formulation reliable aerodynamic messages from visitors and cargo delivery works the bottoms.
