Abstract: Abstract: Shaft coal bunker is a key link in coal mine transportation, its repair and control is difficult. Collapse reason of the coal bunker breakage and surrounding rock collapse in Ganhe coal mine is analyzed in detail, and determines the reasonable and feasible repair design scheme. In the structure design composite support scheme, including anchor, net and reinforce concrete lining. Filling collapsed space with concrete, and do special treatment on the aluminum mudstone strata. Refine the connection form of the key points of the two caol bunker wall and surrounding rock, and the construction steps and effect evaluation was given. The results show that the design can guarantee the construction personnel, equipment safety, improve the caol bunker wall stress state, after the restoration of the shaft coal bunker more stable and durable, to ensure the safe production of the mine.
