    • Abstract
  • Combined with engineering project of belt conveyor go downhill roadway of No. 9 coal in Luyukou Coal Mine, on the basic of UDEC analysis about the influence range and stress distribution law of lower coal by the upper coal wall, FLAC3D is used to study the stress distribution, plastic zone and deformation of the roadway which is inevitable located in high pressure area. The results showed that the roadway in the stress increase area with arch section and reinforced two-side supporting can effectively control the stability, the results has been applied and achieved practical supporting effect.
