Application of Bolt Support Dynamic Information Design Method of Coal Roadway in the Speedy Drivage

Anchor dynamic information design method can adapt to the complexity and variability of the geological conditions of surrounding rock of roadway,the design principle and idea of the method has been accepted by domestic and foreign,it can be suited to the characteristics of the coal roadway bolting design method; it introduced sandvik MB670 type digging anchor machine can realize cutting,loading,supporting,parallel operation into a lane at a time in Changcun Coal Mine. S6- 8 Track Lane adopts advanced MB670 digging anchor all- in- one device and anchor dynamic information design method can realize quick safety and efficiency in coal roadway drivage.
