东欢坨矿地应力测量及应力场分析

In Site Stress Measurement and Stress Field Analysis of Donghuantuo Mine

在区域地质构造分析的基础上,采用空芯包体测量方法,对东欢坨井田两个水平进行了地应力测量,得出东欢坨矿地应力场属于水平应力场,井田内存在着较大的水平构造应力的结论。测量成果为井下工程设计和稳定性分析、巷道合理布局和锚杆支护设计提供了依据。并为进一步研究井田岩体应力状态和应力场的区域预测奠定了基础。

Based on the analysis of regional geology, the hollow inclusion stress measurement method was used on two different horizon places in the Donghuantuo Mine. A conclusion was drawn that stress field of this mine is horizontal stress field, and there lies great horizontal tectonic stress in mine region. Measurement results are helpful to design underground engineering and analyze its stability, and further research rock mass stress state and the regional forecast of stress field.
