| Abstract: | With the width of coal pillars set at 6m and 10m,a roadway in Panel 12203 in Zaoquan Coal Mine was selected as an example.This paper introduced the geological and operational conditions of the roadway in Panel 12203,and analyzed the bolting techniques of roadways adjacent to narrow pillars.The paper proposed a support scheme combining the high pre-tension bolting system with grouting techniques.The results of field tests showed good performance,and the deformation was effectively controlled.The study will provide a scientific base for similar practices. |
