Figure 9
Rockburst failure of roadway at s and 0.5 s of shock wave acting time. Note: the numbers of 1.0, 5.0, and 10.0 m represent the multiple of the original uniaxial tensile strength of immediate roof, respectively.
(a) The acting time of shock wave is s |
(b) The acting time of shock wave is s |
