摘要
介绍了峨口铁矿的地应力测量同时采用的水压致裂法和应力解除法的基本原理和在现场测量中所采用的新技术．根据实测地应力数据，使用静态系统灰色曲线模型获得峨口矿区的地应力分布规律．结果表明由两种方法所获得的测量结果具有良好的一致性．
Both hydraulic fracturing and borehole overcoring methods were used for in-situ stress measurement in Ekou Iron Mine. The basic principles of these two methods and a series of new techniques used in the field measurement are introduced. -Based on the measuring results,the distribution law of in-situ stress state in the Mine was established using grey algebraical cruve model. The measuring results obtained by two different methods showed good agreement.
