Abstract: Roadway surrounding rock was simplified to intact rock represented by Bingham body and weak strata represented by Bingham body，and a dynamic response model of roadway surrounding rock and support subjected to rock burst was established besides its specific application was analyzed．Several techniques such as decreasing impact energy，improving support setting load (working resistance) and support stiffness，and improving support damp and strata damp were put forward to prevent roadway from being destructed by rock burst．They may be transformed into each other between intact rock and weak strata，and when the supporting force is larger，the adjacent weak strata may be transformed to new intact rock so that its strength can become larger while its energy dissipation ability be reduced due to its damping coefficient is becoming smaller．When impact load exceeds the strength of intact rock，intact rock can also be transformed to weak strata，and its damping coefficient is becoming larger (reducing the stiffness of rock) while the strength of surrounding rock is reduced，so "enhanced" role and "deterioration" role also exist．Some methods such as loose blasting，they are good or not depend on which one is larger between increasing damping coefficient and decreasing strength．
