This paper introduces the geomechanics test of surrounding rock of roadway in Wuyang coal mine of Lu’an Mining Administration and its application in the bolt support of coal roof, including the measuring instrument, method and measurement result of underground rock strength; the measurement of small pore hydraulic fracturing stress Device, as well as the measurement principle and measurement results. Based on this, the initial design of bolt support is proposed by the dynamic information design method, the good supporting effect and technical and economic benefits are obtained in the downhole application, and the rationality of the bolt support design is confirmed.
