| Abstract: | The surrounding rock characteristics in the three soft coal seam roadway was analyzed,and pointed out the key technologies of this kind of roadway support,and put forward the present combined support scheme which is practical and feasible,combined with the engineering examples of Linnancang mine and analyzed one of the U-steel and anchor net combined support plan.Which showed that this scheme can effectively control the deformation of the surrounding rock through the numerical simulation and field monitoring.It indicated that U-steel and anchor net combined support is a kind of feasible way in the three soft coal seam roadway supporting. |
