    • Abstract
  • Taking the geological condition of the north main return airway in Suntuan Coal Mine into consideration, we analyze the mechanism of blasting dynamic impacting surrounding rock of roadway by using the method of numerical simulation, it reveals the stress evolving characteristics deformation and failure laws of surrounding rock roadway. The bolt and cable anchor coupling supporting was proposed. The practice proves that the supporting technology is reasonable and better to control surrounding rock movement.
