| Abstract: | In view of the engineering geological conditions of the surrounding rock transported along the channel in the 1109 working face of Sima Coal Industry Company of Lu’an Group,the unfavorable conditions of support are analyzed,and the supporting mode and supporting parameters are optimized.Two measuring points are arranged in the roadway.After monitoring 16 d,the roof and floor and the two sides of the roadway begin to stabilize,and the two sides of the roadway surrounding rock are stable at 230 mm,and the roof and floor are stable at 185 mm,and the support effect is good. |
