Abstract: Aiming at the problem that it is difficult to accurately prevent rock burst，the induced burst law of working face was studied with Xiaozhuang Coal Mine as engineering background. Considering the difference of dynamic and static load monitoring methods，the source monitoring work is carried out. With the help of microseismic method，the dynamic load after coal rock rupture is monitored in the whole mine，and the key working face is monitored by the ground sound method. The static load of coal in local dangerous area is monitored in real time by means of on-line stress monitoring and drilling cuttings sam⁃ pling monitoring. According to the obtained distribution characteristics of dynamic and static load of rock burst in working face，the targeted hierarchical monitoring of rock burst hazard source and the measures of ‘divide source to solve the danger’are put forward，and the solution scheme of rock burst danger for head⁃ ing face and top coal in heading face is formed. This study provides ideas for reasonable prevention of rock burst.

Key words: rock burst, dynamic and static combination, divide source to solve the danger
