FIELD: mining.
SUBSTANCE: offered process of breakdown site isolation involves drilling of wells from the surface into the mine and constriction of stopping facility via them. Along the excavation a number of wells is drilled, and through the end wells walls and roof of the mine are caved, e.g., by explosive charges; caved and solid rock and bulk and tamped by quickly hardening mortar to create rock barriers. The mine between the barriers is filled through the other wells with consolidation stuff, such as sludge or suspension.
EFFECT: enables fast construction of solid gas-proof stopping facilities in the mines when the construction site is out of reach for humans.
