“BRIDGE-CEMENT CURTAIN” CONSOLIDATING ISOLATION SYSTEM CONSTRUCTION METHOD Russian patent published in 2019 - IPC E21D11/10 

FIELD: mining.

SUBSTANCE: invention relates to the mining industry, and can be used in the mineral deposits underground mining in terms of the coal and ore mines mine workings isolation, including during the monolithic insulating structures construction. “Bridge-cement curtain” consolidating isolation system construction method includes the formwork installation, drilling around the mine workings perimeter, injectors in the wellheads installation, the quick-hardening solution injection through injectors into the wells and the marginal zone disturbed rocks fractures, the quick-hardening solution flow into the formwork from the cracks during their filling, the formwork filling with the quick-hardening solution. At that, the formwork is additionally filled with the quick-hardening solution remainder from the cement curtain, discharged from the wells with increasing as the cracks are filled flow rate.

EFFECT: technical result of the proposed technical solution is increase the mines mine workings isolation quality and speed.
