SUPPORT OF UNDERGROUND STRUCTURE Russian patent published in 2016 - IPC E21D5/11 E21F16/00 

FIELD: construction.

SUBSTANCE: invention relates to underground construction, particularly, to support buried structures, and can be used in boreholes subways, coal mines, as well as in vertical openings underground urban infrastructure. Said technical result is achieved by that above and below water head of water pressure in layer set are drilled wells with depth of not less than 0.5 m maximum width of influence of blasting zone in array wells equipped with water intake element consisting of sequentially placed one inside other pipes a control valve on each end; discharge pressure on valves set equal to difference between value of hydrostatic pressure of water head layer and value of hydraulic resistance in area of valve installation space to roof, or confining layer of soil.

EFFECT: providing a roof support structure that avoids penetration of water from water impermeable layer to layer through rock layers containing soluble minerals, while avoiding a substantial increase in water coming into barrel.
