Optimization design of bolt supporting in coal roadway under rapid excavation
Selecting reasonable bolt supporting parameters can not only meet the safety requirements,but also save money and improve efficiency.Based on the analysis of deformation,excavation speed and supporting cost of 91-101 return air roadway before and after a-dopting two supporting parameters,this paper selected more reasonable supporting parameters.Practice has proved that the supporting parameters are desirable under similar conditions.
