MINE SEAL WITH ADHESIVE

摘要

An explosive-resistant mine seal (2) is provided, which includes a pair of block walls (14, 16). An adhesive (22) is provided between adjoining surfaces of the blocks (20) where the adhesive (22) has greater strength properties than the blocks (20) themselves. A core member (18, 18') is provided between the two walls (14, 16) and is bound thereto. The adhesive (22) may be coated over the walls (14, 16) to increase the strength of the mine seal (2).
