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。
The geostrophic stress measurement of Meishan Iron Mine uses the stress relieving method and the improved hollow enveloping stress meter to measure the three-dimensional in-situ stress magnitude and direction at three levels and eight measuring points in the mining area, and obtains the basic distribution of the geostress field in the mining area through statistical analysis law. The measured results are basically consistent with the tectonic stress field of the mining area based on the tectonic line.
