摘要: 本文介绍了空心包体应力解除法在安庆铜矿-580m中段地应力测量结果,对矿区应力分布特征进行了探讨。实测表明,在-580m中段最大主应力的大小是24MPa,最大主应力方向由NE到近EW向。该矿区地应力以水平应力为主导,水平应力大于铅直应力。Abstract: In this paper, the results of rock stress mesurement of -580m level by hollow inclusion gauge at Anqing coper mine are introduced, the characteristics of stress distribution are discussed. The mesurement results show that the magnitude of the maximal principle stress is 24MPa, its orientation is NE to EW. The horizontal stress is in the dominating position and it is bigger than verticle stress. The measurement results can apply to mine design.
