Abstract
Based on supporting failure mechanism and time and space function law of surrounding rock deformation, using the FLAC3D numerical simulation analyzes the bolt mesh cable coupling support of roadway in time support and lagging support. Support in time covers high strength and high strength and pre tightening force of anchor bolt, sagging support covers high strength and high pre tightening force of cables with rigid support. Through the numerical simulation, the timing of the second coupling support is determined, the distance of lag support with the anchor cable is 30m. The engineering practice shows that the whole stability and stability of the roadway can be improved effectively by using the bolt mesh cable coupling support in the deep high stress roadway. The force of surrounding rock is more stable, and the deformation is controlled effectively, which is of great significance to the safe and efficient production of coal mine.
