The in situ crustal stresses measurement and calculation of stresses by finite element method are carried out in Yanshitai Coal Mine. The effect of crustal stresses on rock burst are analyzed.Based on the strength test of coal, a criterion is set up. The criterion of energy is put forward in the light of engineering practice.Finally,the zone prone to rock burst in No.6 seam is evaluated.
