In-Line Loading Chute Technology • Full ore pass burden and entire chute weight carried by rock box support beams • Loading chute module easily detaches from rock box and transported to another rock box installation • Sequential ore pass haulage point development costs are greatly reduced by transferring loading chute module to new

Ore passes are used to drop mined ores in to underground bins and loading points. From there the ores can be hoisted to the surface. The ore in ore passes can be unloaded through side discharge chutes (box fronts), or underflow chutes.

The loads acting on any box front are a function of several different parameters. These include natural, operational and excavational parameters. A case study analysis was carried out using UG2 ore and a typical box front structure to demonstrate the relationship between the mass of the box front and the material
