Abstract: Giving a discussion on the mechanism of high rock velocity in rockburst, the rock velocity is estimated from the perspective of flexible loading and rigid loading; then the mechanism of it is explained from the point of the buckling of transverse constrained plate, the constraining condition of plate is also discussed, the energy of destroyed rock is analyzed. The result shows that the velocity of rock may reach 10 m/s and the tensile strength of rock also influences the velocity.

Key words: rockburst, buckling instability, constraint, velocity
