According with the supporting status quo of steeply inclined seam roadway,in experimental laneway the application of Bolt-mesh-anchor support system was explored.The surface displacement and deep displacement of surrounding rock of experimental roadway,and bolt/cable pressure were monitored in-situ.This paper analyzes the deformation of surrounding rock of experimental roadway.The experiment showed that bolt-mesh-anchor support system could be applied to support steeply inclined seam roadway,This provide basis for supporting parameters design and the popularized application of Bolt-wire mesh-anchor support system in steeply inclined seam roadway.
