Research and Application of Dynamic Coupling Support Technology for Large-angle Three-soft Coal Roadways with Large Dip Angle
The single rigid passive support form of metal support is mainly used in the excavation of large-angle three-soft coal roadways,which has poor supporting effect and is easy to deform.In order to solve the above problems,a dynamic coupling support system for large-angle three-soft coal roadway was studied,and multiple anchor time indication devices were added to the main support structure.Through geology evaluation of the three-soft coal roadway,multiple original geology parameters of the three-soft coal roadway were obtained,initial support parameters were generated,on-site support system was set up and real-time monitoring was carried out.According to dynamic geology parameters and dynamic support parameters,feedback information was generated to optimize the dynamic geology parameters and the dynamic support parameters of the support system of the three-soft coal roadway in time,and the unset part of the support system was modified according to the optimized support parameters.Through the dynamic coupling support method and system of the large-angle three-soft coal roadway,the best supporting time was obtained and better supporting effect was achieved.
