FIELD: mining.
SUBSTANCE: modular support of vertical shaft includes reinforced-concrete modules with projections, which are located on edges; modules have lifting lugs and arched tubes; water removal system is arranged in the support body, and space between external projections of modules is filled with mixture of activated tailings of ore concentration of the first and the second turns, granules of foamed polystyrene and larger filler with the size of up to 20 mm.
EFFECT: reduction of installation labour intensity of modular support, creation of zone with adjustable deformation at action of pressure on the side of rocks and providing the controlled operating mode of the support under action of increased hydrostatic pressure.
