Due to the early years of mining makes Gob fracture zone, the deformation of rock fracture zone, and gradually developed through. Located in the mined-out area causing tension within fractured zone of discontinuous deformation region arsenal varying degrees of ground and walls to crack, great security risk to the normal operation of the arsenal caused. Project uses Sleeve Valve Pipe and Steel Pipe Micropile reinforcement scheme. This paper describes the details of the reinforcement mechanism, the construction process, technical requirements and quality assurance measures. Practice has proved that the joint reinforcement program can continue to crack the wall of effective governance to ensure the safe operation of the security arsenal.
