Distribution Law of In-situ Stress for Xiegou Mine and Its Application

In order to study the stress distribution law of Xiegou Mine, the geostress of Xiegou Mine was tested by the small pore hydraulic fracturing stress measurement method. The main stress level, main stress field type and stress direction are studied. The influence of in-situ stress direction and roadway layout direction on the deformation of the roadway are analyzed, which well guides the roadway layout and support parameters selection with good results.
