A barrier for a passage is configured to close off a zone in an enclosed environment, for example for a drift in a mine to close off a zone in the mine. The container may be least partially flexible and expandable, by being formed of woven fabric. A supply pipe for an hydraulic fill extending from outside the zone into the zone, and a drainage pipe can be provided for permitting fluid to drain from the zone. These pipes may extend through or around the container. After placing the container in the passage, the container is expanded to form a barrier in the passage, to close of the zone, except for the pipes. The container is filled with hydraulic fill, e.g a slurry. After forming the barrier, further hydraulic fill is supplied to the zone to fill the zone, with the barriers containing the fill in the desired location.
