中文摘要:
      对东滩煤矿三采区地应力进行了现场测试及非线性有限元计算,分析了地应力对冲击地压的影响。通过煤体强度实验建立了其强度准则,并结合工程实际建立了能量判据。在此基础上对该矿3号煤层冲击地压的区域危险性进行了评价。
英文摘要:
      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.
