Abstract
Based on research fruit and engineering practice of mining large inclined angle coal-seam,this paper simulated characteristic of roof caving and stress distribution of surrounding rock in coal mining by FLAC3D.Stress distribution rule and deformation characteristic of upper and lower face-end,mining influence range were mainly analyzed from tendency and strike direction.Mechanical characteristic of mining coal-seam with large inclined angle was obtained.
