SEALING INTERMEDIATES FOR SEPARATION OF MINE ISOLATED HORIZONTAL PROCESSING AND METHOD OF ITS FACILITIES Russian patent published in 2018 - IPC E21F17/103 E02D19/18 

FIELD: mining.

SUBSTANCE: group of inventions refers to the mining industry and may be used to isolate a part of mine horizontal excavations from watering or from penetration of excess gas and liquids from underground storage facilities. Sealing jumper includes a concrete body embedded in the contour cut, a peripheral metal reinforcement, a contact layer with a rock massif and at least one pipe passing through the concrete body. In this case, the peripheral metal fittings are made of longitudinal and transverse bonds, the transverse bonds, except for the extreme ones, are made in the form of belts with depressions, in which torus-shaped perforated elements are placed, for example made of elastic material, each cavity of which is connected by at least one pipe, moved outside the end face of the concrete body from the side of the protected part of the horizontal excavation, and the pipe passing through the concrete body is equipped with a gate valve.

EFFECT: technical result is an increase in the efficiency of the waterproofing of the bridge along the contour of the mine horizontal excavation by eliminating the negative influence of various deforming abilities of the material of the body of the bridge and rocks by changing the density of the material of the contact sealing layer during the construction of the bridge.
