山西麻家梁矿地应力特征研究

Study on Ground Stress of Majialiang Coal Mine in Shanxi Province

为了研究麻家梁矿地应力场分布特征,在麻家梁矿14103和14203工作面辅运巷内分别布置了4个测点,采用空心包体应力解除法进行了地应力测量,然后采用有限元模拟方法对研究区进行了地应力场的反演分析。

In order to study the ground stress of Majialiang coal mine,four measuring points were arranged in 14103 and 14203 auxiliary transport roadways in Majialiang coal mine,the ground stress was measured by using stress relieving method. The inversion analysis of ground stress field was carried out with the method of finite element simulation.
