ABSTRACT:
A pumpable mine assembly is provided having a pair of steel support structures forming the front and back surface of the seal. The support structures can be formed by either a row of vertically-disposed steel beams or a cable lattice secured by anchor bolts to the top and bottom surface of the mine entry. A separate wire mesh backing is provided on the inside of each of the pair of support structures. A seal bag placed within the wire mesh backing receives filling material, generally in the form of concrete. The filled seal bag forms a tight seal on the top, bottom and ribs of a mine entry or passageway.
