According to the requirement of stability analysis for karst cavity and in-situ stress analysis,conditions of drilling-dissolving mining for deep rock salt mine,and practical experience of research on in-situ stress measurement in deep rock salt mine,the selection principle of measurement methods,measured points and samples are determined. The method of building up the coordinate direction of non-directional drilling cores in sediment strata is proposed. Based on the principle of in-situ stress measurement by the Kaiser effect of acoustic emission,the multidirectional sampling and the ellipsoid regression analysis of in-situ stresses are made. Multivariable nonlinear fitting is made to determine a general form of in-situ stress ellipsoid,and then a quadratic orthogonal transformation is made to determine the standard equation of in-situ stress ellipsoid,so that the magnitude and direction of three principal stresses can be obtained. The presented method can avoid more effect of testing errors and get reliable measurement results. According to the testing and analysis results from Changshan Salt Mine,there is horizontal tectonic stress in deep strata,and the direction of major principal stress turns to vertical direction from horizontal direction at the depth of 800 m,and at the depth of 1 000 m the major principal stress is about 30 MPa.

针对深部岩盐矿溶腔稳定性分析及地应力场分析的要求和深部岩盐矿钻孔水溶开采的条件,结合长山岩盐矿深部地应力研究的实际情况,确定了矿区地应力测试方法、地应力测点和试样选择的一些要求;按照声发射Kaiser 效应测地应力的基本原理,提出了沉积岩层非定向钻孔岩芯坐标方向建立的方法和多方向取样及地应力椭球回归分析的声发射 Kaiser 效应地应力测试方法。该方法根据三维空间多方向试样的 Kaiser 效应实验结果,采用多元非线性拟合方法确定测点地应力椭球的一般方法,再由二次正交变换确定测点地应力椭球的标准方程,以求得地应力的大小和方向。此方法能避免实验误差的较大影响。长山岩盐矿实验矿井深部地应力测试结果及分析表明,长山岩盐矿深部存在水平构造应力,最大主应力方向在离地表 800 m 深左右由水平方向转为垂直方向;距离地表 1 000 m 左右深的岩盐层中,最大主应力一般为 30 MPa 左右。
