This invention relates to particulate material retaining bags for wall construction and erosion control and in particular to such bags for use as mining backfill bags as illustrated. The backfill bag (10) comprises a plurality of tubular bags (12) made from a fluid-pervious (weeping) fabric, juxtaposed lengthwise and extending parallel to one another. Each bag has a filling inlet (14) for feeding mine backfill (a fluid fill material constituted by a particulate material entrained within a transporting hydraulic fluid) into the bags (12). The bags (12) are secured to one another along upper and lower securement zones extending along the juxtaposed sides of the bags (12). |
