Abstract: in view of the support control problems,such as large deformation and severe support structure damage of fragile coal-roek roadwayunder complex geological conditions,this paper took No.1301 haulage roadway as the research object and on-site engineering research and laboratory test as the methods,concluded the deformation and failure mechanism of coal-rock roadway.put forward to an integrated and optimized supporting scheme-whole anchor cable(ong and short anchor cable) +metal net + steel belt and analyzed the supporting effects of original schemeand optimized scheme contrastively by FLAC3 Dsoftware. The results showed that,the optimized scheme effectively controlled the deformation ofsurrounding rock of the roadway and released the surrounding rock stress to a greater degree,which formed a relativly integrated system.Accoding to the site monitoring,final convergence of two roadway sides was 327 mm and roof and foor 239 mm,and later convergence got smaller and stable; anchor cable press increased quickly in frst 20 days and then decreased ,but the anchor force reached to a high stable value eventallywhich effectively controlled the large deformation of roadway.
