Abstract: At present, there is no precedent for reserving a withdrawal roadway for equipment retreat in Huanglong mining area.Taking the thin coal seam 119 fully mechanized mining face of Ruineng Coal Mine as an example, we propose a retreat method for reserving withdrawal roadway and its engineering application.Key technologies such as reserved withdrawal roadway support, final mining breakthrough control, and passage roadway pressure monitoring are summarized.Before the fully mechanized mining face advancing to the reserved withdrawal roadway, the withdrawal roadway must be reinforced with “active+passive” support mode; Reasonably set up comprehensive mine pressure monitoring stations within the reserved withdrawal roadway, strengthen mine pressure monitoring, adjust the support inside the withdrawal roadway in a timely manner, and strictly prevent the collapse of the reserved roadway.
