Abstract: Rock burst is one of the most serious dynamic disasters in the process of coal mining,which poses a great threat to the safety of coal mining. Statistics show that 85% of rock burst occurs in the roadway,resulting in damage,collapse and even closure of the roadway and casualties. Roadway support has become the last line of defense to prevent rock burst. Based on the analysis of surrounding rock failure process and key influencing factors of rock burst roadway,the technical and implementation method of shock reduction and isolation in deep mine rock burst roadway are studied,which effectively protect the overall stability of surrounding rock structure of roadway. The principle of support and isolation technology for rock burst roadway is proposed. Isolation technology is to form loose coal and rock mass with significant wave absorbing and energy absorbing effect by cracking between supporting layer and original rock. The energy absorbing mechanism is mainly reflected in four aspects:loose block energy absorbing,rotating block energy absorbing,space scattering energy absorbing and reflection energy absorbing. Reduce technology through the large elongation and yielding displacement of supporting components such as anchor cable,O-shed and anti-scour unit frame,and through the strong scattering and energy release effect of damping supporting components,the overall mobility and yielding displacement characteristics of roadway supporting anchor solid under instantaneous high impact dynamic load are protected. The double combined protection effect of“isolation + reduce”realizes the performance characteristics of the whole energy release and anti-scour of the surrounding rock support for wave dissipation and load reduction,maintain the stability of the surrounding rock of the roadway with rock burst. The field practice and microseismic monitoring show that the technology of reducing isolation can effectively control the deformation and failure of the impact ground pressure roadway,the micro earthquake energy of the roadway surface monitoring is reduced by 50%,and the supporting effect of the roadway is remarkable.
