A bulkhead for use in facilitating backfilling of a stope upon mining thereof includes a skid having a base and a pair of post members extending upwardly from the base. The bulkhead also includes a barrier having a primary grid assembly pivotally supported on the pair of post members, at least one secondary grid assembly selectively, and sequentially, stacked upon the primary grid assembly; and a brace selectively stacked upon an uppermost one of the primary grid assembly and the at least one secondary grid assembly. An aspect ratio of the barrier, prior to, backfilling, is operably adjustable by individually adjusting one or more of the primary grid assembly, the secondary grid assembly and the brace to confirm with an aspect ratio of an access tunnel, or a brow, adjacent to the stope for subsequently facilitating backfilling of the stope.
A bulkhead (100) for use in facilitating backfilling of a stope upon mining thereof, the bulkhead (100) comprising:
The bulkhead (100) of clam 16, wherein each of the at least two slidable clamps (170) includes a front plate (172), a back plate (174), and a bolt and nut arrangement (176) to secure the front plate (172) to the back plate (174) for adjustably, and independently, coupling the arcuate tube member (166) to corresponding ones of the at least two upright members (164).
