Abstract: Fore to the 9-10-2218 working face when finishing equipment cannot routinely retracement, and close to instability of coal seam roof, from the face began to surf the Internet to the final device retracement, rewind support scheme was proposed, and a retreat channel anchor net + anchor combined support and "the anchor section no timber supporting" process, optimization of construction parameters, innovation to implement the nose triangle preconditions such as complete sets of technology. The results show that the technology of the reversing equipment is reasonable, the combined support of the retracting passage and the construction parameters of the wiping Angle can meet the requirements of the retracting equipment, save time and materials for the pressure relief roadway and ensure the safe and rapid recovery of the working face, which can provide a reference for the retracting of the same type of working face.
