Flexible Storage Control Principle and Application for Rock Burst Roadway

Deep roadway rock burst prevention has become a problem to be solved urgently, according to the mechanism and failure characteristics of rock burst roadway, strong-weak-strong control principle was proposed based on relief-support coordination, by reducing the impact of source disaster, setting energy absorption structure and improving the weak structure support strength, can effectively control the impact damage on roadway. Finally, according to the actual situation of a coal mine, using anchor net +"O" type shed combined support structure, although multiple burst events during the trial period, the double support structure has a flexible deformation, the flexible deformation makes the impact energy release, the supporting system remains intact and has a good control effect with rock burst disaster.
