| Abstract: | By analysis on the geological data of 11-2 mining coal seam in Liuzhwang Coal Mine,in combination with some characteristics,such as its burial depth,and poor stability of surrounding rock,roof pressure significantly,the combined support with semi-circle anchor mesh cable was applied in the construction process of the up and down crossheading at 121105 working face. The roadway deformation was effectively controlled. |
