摘要：
The creep feature of the rock mass must be considered in deep mining. The constitutive equation of surrounding rock is described by liner viscoelastity. From the model of the thin vicsoelastic plate, the calculation formula of the critical time on the slab stability is derived. The creep buckling of the slab is dependent on the material behavior. The value of critical load on slab is a range relates to time. Under given load, buckling will occur in a time delay. At last, the effect of the turbulence stress for the rockburst is studied.
