摘要

FIELD: mining.;SUBSTANCE: mine excavations fastening method during potassium salt field's development concludes in anchor bolts installation with rock bolting support and counterforce elements, the rock bolting made of polymer material Cover the rock surface between anchors with a protection element, made of polymer cloth, which does not allow moisture and water vapors penetration, at least in one side direction The polymer cloth fixed to the rock surface by pressing it to the rock with support elements The pit bolting for the rock excavation fastening during potassium fields development contains anchor bolts made of polymer material as bearing rods with support and counterforce elements, support slabs, installed between support elements and a mine roof rock, claw nuts and the protection element as a polymer cloth, which does not allow moisture and water vapors penetration, at least in one side direction, fixed on the mine roof with support slabs.;EFFECT: decrease of water vapor and pit aggressive waters influence on a mining equipment, operation casts decrease, undergoing mining equipment lifetime increase.;4 cl, 1 ex
