STRESS MEASUREMENT OF ANQING COPER MINING

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.
