| Abstract: | In this paper,the 3-5^#layer panel belt roadway in Yongdingzhuang Mine is taken as the research object.Aiming at the engineering problems such as easy roof caving in the igneous rock intrusion area,poor anchoring effect of anchor cable and so on,the support design of the whole broken coal roadway is carried out.According to the actual engineering situation of the optimization design test section of the roadway in the igneous rock intrusion area,a reasonable numerical model is established,and the support effect of the roadway during the driving period is simulated and analyzed,and the optimal tunnel support scheme is determined. |
