Abstract This paper introduces the restoration plan, key points and construction process of steel structure engineering of mine conveying corridor. The instability of the slope leads to the crushing of the mine and the damage to the basic steel structure of the belt conveyor of the conveying system and the displacement of the truss. In the environment where large-scale hoisting equipment cannot be used, the truss and other components to be replaced are suspended to the design position by means of suspension bridge transportation. Repair processing was carried out, and the main sling load and safety factor of the gantry frame were checked. The method is less destructive to the environment, simple in operation and strong in adaptability.
