A construction of timbers laid at right angles resembling a log cabin. This was often used to line vertical shafts to hold back loose rock and dirt. However, cribbing could also be used to support the roof of a mine or equipment. With time cribbing may dislodge causing a complete blockage that later gives way leaving a gaping hole.
