Abstract:
Energy check design method for rock-burst roadway was put forward based on energy theory of rock-burst.It included two phrases: firstly,applying modern and advanced roadway design method for initial design;secondly,checking the design based on the judgment whether the deformation energy of supporting system was enough to consume residual energy released during surrounding rock damage.The design progress was: evaluating rock-burst danger in roadway;calculating residual energy;preliminary designing and checking energy absorption of supporting system.Main components’ energy absorption index of Chinese anchored bolt was calculated and an application example using the method was presented.
