The analysis of the bolted roadway stability with discrete element method
The model is generated in the paper taking the fully mechanized caving face in Yang-village mine,Yima group as engineering background,using UDEC software to analyze the influence of joint characteristics parameters on surrounding rock stability of fully-mechanized caving roadway,and from the aspects of the horizontal compressive stress between joint surfaces of roof,the roof sinking magnitude and surrounding rock failure,the fully-mechanized caving roadway is simulated with different anchorage forms and bolt length,with pallet and steel belt or not,different block sizes and different buried depths1.Through improved roadway supporting technology,the supporting effect was increased,the damage and destruction of the supporting to rock mass was reduced.The computed results were consistent with practical application.This shows that the technology has some directive significance for mining under the same geological conditions,and supports theoretical and practical basis for the mines safety in production and sustainable development.
