Abstract
Huafeng mine 1141 roadway (the 5th) that the buried depth is nearly 1000m, the angel of roadway is larger, the physical and mechanical characteristics of surrounding rock are poor, belongs to typical large inclined angle soft rock deep roadway. Using the reasonable supporting way is very important to control the deformation of the surrounding rock in roadways. The strata control observation shows that the roadway deformation is in a predictable range, could effectively ensure the stability and service life of 1141 roadway (the 5th) by using combined support of anchor, bolting with band and net, composite U shape shed. It can provide reference function to the supporting way of similar deep roadway.
