Highlights

The orepass is an important project to slide ore，its structure is simple and convenient to use，but after long-tern use，because the ore constantly impact and wear the orepass wall，it is easy to occur the phenomenon of orepass wall collapses.For most mines，there are some difficulties in the maintenance and repair of chute，so it is necessary to choose a safe，effective and reliable technical scheme for chute reinforcement.Aiming at of the disadvantage of existing support methods that occupying the chute with long construction time，a technical proposal for the integrated reinforcement using double-controlled tension cable bundles from the periphery of ore pass to the inside of it was proposed，and the principle of its action is also described.By establishing the mechanical model of double-controlled tension cable bundles，the design method of cable load that satisfied the safety factor was analyzed.Combined with field engineering practice and monitoring data analysis，it’s proved that the double-controlled tension cable bundles can make the collapsed wall stable for a long time after being reinforced，and can save plenty of repairing time by reducing the occupancy of the ore pass.The method for repairing collapse of ore pass wall based on double-controlled tension cable bundles provides a feasible way to solve the problem of repairing large-scale collapse of the ore pass wall in a safe and efficient way.
