岩体的初始地应力是地壳地层力学状态最基础的原始数据,是采矿工程围岩稳定性分析、开采与支护设计的一个基本参数。采用KX-81型空心包体应力计实测了薛湖矿区2个测点的三维地应力大小和方向。通过结果分析表明薛湖矿以水平压应力为主导,确定了取向为118.47°、最大压应力为37.36 MPa的区域现今构造应力场。测量结果对深部采矿设计和安全生产具有重要的指导意义。
The initial geostress of the rock mass is the most basic raw data of the mechanical state of the crust stratum and is a basic parameter of the stability analysis, mining and support design of the surrounding rock of mining engineering. The size and direction of three-dimensional earth stress of two measuring points in Xuehu mining area were measured by KX-81-type hollow inclusion stress meter. The results show that the Xuehu deposit is dominated by the horizontal compressive stress, and the present tectonic stress field is determined in the area with the orientation of 118.47 ° and the maximum compressive stress of 37.36 MPa. The measurement results have important guiding significance for deep mining design and safety production.
