Measurement and the Distribution Law of In Situ Stresses of Tingnan Coal Mine

Abstract:

In order to study the distribution law of in situ stress field of Tingnan coal mine, 4 points of in situ stress measurement were carried out in underground roadways at the -450 m level with the overcoring method. The KX-81 type cell was used to measure the 4 points of in-situ stress. According to the analysis and calculation of the measurement result, the dominant factor of the in situ stress field in Tingnan coal mine at the depth of -450m is horizontal tectonic stress.
