Research on application of differentiated supporting scheme of mining roadway in Youzhong Coal Mine
In response to the problem of deformation differences in the surrounding rock of different sections of the No.150202 roadway in the No.15 coal seam of Youzhong Coal Mine,based on the excavation equipment and the roadway surrounding rock detection results,the surrounding rock was divided into sections with normal geological conditions,sections affected by faults(structural zones),sections with broken surrounding rock,and special sections such as large sections and intersections.Using the principle of differentiated support-ing,an overall supporting plan was designed for the mining roadway of the No.15 coal seam in Youzhong Coal Mine,and efficient sup-porting plans for different sections were proposed accordingly.The rationality of the differentiated supporting scheme was verified through monitoring the rock pressure manifestation and deformation of the No.150202 return airway.
