| Abstract: | Taking north-six roadway of Taoyuan Coal Mine,Huaibei Mining Group as the research target,this paper analyzes surrounding rock pressure appeared characteristics under the influence of the north-six roadway by riding mining 7246 face and 8246 face.According to the observed data,analyzes the deformation rule and destruction features effected by mining roadway.With the help of numerical simulation,the stability characteristics of roadway affected by riding mining in coal seam mining are analyzed and obtains the surrounding rock stress and plastic zone range. |
