| 摘 要： | 梅山铁矿地应力测量采用应力解除法和改进型空心包体应力计，测量获得矿区３个水平８个测点的三维地应力大小和方向，并通过统计分析得出矿区地应力场分布的基本规律。实测结果与依据构造线推测的矿区构造应力场状态基本一致。

| Abstract: | In situ stress measurement in Meishan Iron Mine was completed with stress relief by overcoring technique and improved hollow inclusion strain cells. The magnitudes and directions of in situ stress at 8 points in 3 levels were obtained. By statistical analysis, the basic regularities of in situ stress distribution in the mine were concluded. The measuring results showed good agreement with the tectonic stress in the mine region. |
