Abstract：Current support in coal mines cannot solve rockburst effectively. The basic problems of support form and method in coal mines are analyzed. Based on the theory of deep rock mass of a complex hierarchy of blocks structure which is discontinuous and self-balance stress rock mass，a theoretical model of discontinuous overburden blocks-rock and support crossfeed action is presented. The effect of support performance on the overburden block-rock dynamics response is studied when the shock load propagates in the discontinuous and self-stress block-rocks in form of pendulum-type wave. We came to the conclusion that：acceleration amplitude of overburden block-rock which close to support declined obviously when increasing stiffness of rigid support；acceleration response time of overburden block-rock shortened significantly when addition damping to support，which has energy dissipation mechanism to rigid support. Based on the two points，support with the coupling effect of rigid and energy dissipation mechanism is better to enhance the stability of surrounding rock and enhance the ability of support-surrounding rock system resistance impact. It can prevent rockburst serious result. We put forward the design of rapid energy-absorption and abdication anti-shock rigid-flexible coupling support，and briefly introduced the new energy-absorption and abdication anti-shock hydraulic support. The core component of energy absorption is analyzed preliminary. The results of this paper can provide a basis for development of series energy-absorption and abdication anti-shock support equipment and improving support method，formation a new anti-shock support technology and method.
