| Abstract: | The in situ terrestrial stress me asurement and calculation of stress by fini te element method were carried out, and the effect of terrestrial stress on rock burst analyzed. Based on the strength testing of coal, a strength criterion is set up .The cr iterion of energy is put forward in the ligh t of engineering practice. Finally, the ris k zone of rock burst in No.3 coal seam is eva luated. |
