摘　　要：目前,铜矿峪二期工程进入410 m中段开采。该段开采结束后,将转入深部工程开采。随着开采深度的不断增大,将面临地应力增大所带来的问题。以铜矿峪矿地应力场和深部岩爆预测为研究对象,采用应力解除孔壁应变法对800~870 m水平的原岩应力进行测量,得出了铜矿峪矿区地应力场的一般规律,并在220~410 m水平开展了18个钻孔岩心物理力学参数的测量,结合Barton法、国标法和陶振宇法等判据,完成了对220~410 m水平深部开采区域的岩爆预测分析。Currently,the Copper Mine Valley Phase II project has entered the 410 meter middle section for mining.After the completion of this mining section,it will be transferred to deep engineering mining.As the mining depth continues to increase,it will also face the problem of increased geostress.Taking the in-situ stress field and deep rock burst prediction of Tongkuangyu mine as the research object,the stress relief hole wall strain method was used to measure the original rock stress at the level of 800~870 meters,and the general law of the in-situ stress field in Tongkuangyu mining area was obtained.18 physical and mechanical parameters of drilled rock cores were measured at the level of 220~410 meters.Combined with Barton method,national standard method,Tao Zhenyu method and other criteria,the rock burst prediction analysis of the deep mining area at the level of 220~410 meters was completed.
