ABSTRACT:
A reusable mine and underground roof, floor and rib support system including a horizontal chamber or entry and a tail assembly. The horizontal chamber is composed of individual pieces assembled to form sections of the horizontal chamber which can easily be disassembled and reused. The tail assembly is an individual and separate unit located at the end of the horizontal chamber adapted to accommodate dismantling the horizontal chamber sections using jack and cable winch systems. The combination of horizontal chamber and tail provides a underground entry that will allow roof collapse, floor heave and rib failure and remain usable.
