Abstract

Fault fracture zone due to the loose and broken surrounding rock of roadway, tectonic stress, the surrounding rock deformation is hard to control, has been one of the difficulties in roadway support technology research. This paper aim at Xingcun coal mine-1196m level roadway through extra large fault fracture zone, large deformation of surrounding rock and failure supporting project, can t ensure the overall stability of the roadway, put forward the “Bolt-mesh-spurting + prestressed hollow grouting anchor” combination support, effectively control the surrounding rock deformation in the test section of roadway, successfully resolved the problem of long-term stability of the surrounding rock in the fracture zone.
