Abstract：In order to understand dangerous situations of work face, to take prevention measures in advance and to reduce late treatment intensity, the correlation between concentrated static load and rock burst is analyzed. A model for burst hazard assessment is established based on the detection of centralized static load, and it is put into practice. The results show that the concentrated static load plays a dominant role in the initiation of rock bursts, and it can be surveyed and unloaded before the mining of work face. The regional centralized static load can be surveyed by using the seismic CT. The proposed model for burst hazard assessment based on seismic wave parameters can be employed to evaluate the dangerous situations of work face and to guide the implementation and check of the control effect of prevention and cure work.
