FIELD: mining.
SUBSTANCE: anti-explosion barrier 1 comprises multiple identically arranged so called double water pockets 5. These double water pockets 5 comprise a sleeve made of a polymer film 4, which is bent at the ends 15 with formation of an edge or a channel, or a valve (7, 12) for insertion, and then it is welded, sewn or stitched. Via a channel or a valve 7, 12 formed in this manner for insertion an intermediate rod 10 is stretched, and then suspended to s-shaped bearing hooks 8, 9, which at their side by means of another hook are installed on the bearing rod 2. As a rule, aside, in the zone of entry for an intermediate rod 10 there are through holes 20, 21 provided, or loading holes 6, through which water 11 may additionally enter, and if necessary, again drain. Therefore only one of parts 13 of the pocket shall be removed from the s-shaped bearing hook 8 or 9 and is lowered down, so than then water 11 could be quickly drained via the specified holes.
EFFECT: barrier is easier mounted and dismantled, easily filled with water, and quickly and simply carried, if necessary.
