【摘要】 本文在总结深井冲击地压的特征和规律的基础上,对深井冲击地压的发生机理,如强度理论、冲击倾向性理论、刚度理论、能量理论、失稳理论等分别进行了分析,指出了上述各种理论的不足,结合淮北某矿顶板砂岩试验,提出了利用应变法和声发射法来预测深井冲击地压的发生,取得了较好的效果。更多还原

【Abstract】 Basis on the character and features on deep mining rock burst,this paper analyzed the deficiency of its mechanism such as theory of strength,concussion orientation theory,energy theory and unsteady theory,etc.In addition,the paper put forward two forecast methods,that is,the strain method and acoustic emission method.The roof sandstone test of certain coalmine in Huaibei indicated a good effect.更多还原
