A prefabricated cribbing column for supporting a mine roof. The column
includes a plurality of concrete cribbing elements the majority of which
are interleaved with load transfer disks. Two of the cribbing elements
are interleaved with a handle element. The column assembly of cribbing
elements, load transfer disks, and handle element are secured together in
an integral unit by a steel strap. The handle element extends
substantially beyond the outer periphery of the cribbing elements
enabling access and lifting by a forklift or similar machinery. The
handle element enables the integral column to be easily moved from one
location to another. The cribbing elements are preferably constructed of
steel fiber reinforced concrete. A column consisting of five cribbing
elements has shown to be capable of supporting a load of 575 tons with a
deflection of 2.5 inches or less.
