Based on Tunlan Mine 28107 roadway (half rock coal roadway) large slice resistance, low half rock coal roadway drivage speed, affecting normal working face replacement and other problems, combined with the actual geological conditions and the existing supporting method, roadway support way was analyzed by FLAC3D simulation, the results showed that, in the cases 1.0 m and 1.2 m roadway bolt row spacing, both of the supporting methods can ensure the effect of the roadway, and the 1.2 m row spacing can improve drivage and supporting supersedure problems, greatly enhance driving speed.
