Abstract

A fire wall, blast wall or containment wall for underground stopes and other areas is built by bringing underground empty bags which are filled with broken rock, stones and sand, laying them in one or two rows stretcher bond in the form of an arch whose ends are buttressed against the sides of the stope, etc. A steel mesh is on the concave side or between the two rows if there are two rows and wires are used to bind the bags using loops provided on the bags to the mesh. A ballast of broken rock and dust is piled up on the concave side of the wall, contained between the bag wall and a back wall.
