There are many in situ stress measurement methods nowadays, the ISRM suggested two methods for in situ stresses measurement: overcoring methods and the hydraulic fracturing methods. In order to study the distribution law of in situ stress field in the deep position of Hongyang coal mine, 3 points of in situ stress measurement were carried out in underground roadways at the -870 m level adopting the overcoring method. The KX-81 type gauge was used to measure the 3 points of in-situ stress. According to the analysis and calculation of the measurement data, the result showed that the in situ stress field in Hongyang coal mine at the depth of -870m was dominated by horizontal tectonic stress.
