Abstract The self-weight stress and tectonic stress control the basic stress level of coal face，and the mining-induced stress caused by the moving of overlying strata contributes the most to the rock burst hazard. The multiple structures and movements of covering rock result in the complex mechanism and various types of rock and a burst. The relationship between the coal face boundary and overburden structure was studied，and a three-zone structure loading model was established. The influence of overlying rock structure on the stress field of rock burst was analyzed(mainly on the strike and dip abutment pressure induced by the movement of roof strata). According to the model，a monitoring and prevention method of rock burst was proposed. With the three-zone structure loading model，the type and grade and the risk of potential rock burst were classified.

Key words： mining engineering rock burst roof structure abutment pressure three-zone structure loading model rock burst hazard
