To study the support technology for broken surrounding rocks, drilling peep instrument was used to analysis the situation of broken surrounding rocks of roadway and roof. On the foundation of this detection, combining the experience of practice, the author proposed the method of incorporating of high pretension force anchor and cable, wire netting, W steel band and concret spaying over the roadway. The mine pressure indicates that the supporting parameters and method used in the study of roadway effectively control the deformation of surrounding rock in broken surrounding rocks.
