Numerical Simulation of Anchored Bolt Supporting for Roadway in Small Coal Pillar with Large Inclined Angle

This paper analyzed supporting mechanism of roadway with anchored bolt in small coal pillar and simulated roadway stability and surrounding rock’s deformation of roadway in small coal pillar.Result showed that anchored bolt with high strength could control effectively deformation of surrounding rock and anchored bolt was most effective supporting manner for roadway safe and pillar stable.
