Ore passes often lead to an underground storage bin to provide surge capacity in the ore stream. In turn, the ore is normally drawn off the bottom of the bin into a chute. The design of passes, chutes, and bins was once a simple exercise and the operations were relatively trouble-free. Today, many hard rock mines experience acute problems ...

Chute flow patterns are described and the application of chute flow dynamics to the determination of the most appropriate chute profiles to achieve optimum flow is illustrated. The influence of the flow properties and chute flow dynamics in selecting the required geometry to minimise chute and belt wear at the feed point will be highlighted. 1.
Chute loading/transport. The ore is transported from the rock bins at the ore pass to huge crushers. In Kiruna, transport takes place using driverless trains to the main level, 1,365 metres below ground. In Malmberget, where mining is performed in several ore bodies at the same time, the ore is transported to the crushers in large trucks.

in Underground Mine Ore Passes the ore pass was in excess of 27,300 kg (60,000 1b); however, a maximum static load or only 6,800 kg (15,0001b) was measured, which was approximately the weight Of the waste material needed to fil the chute itself. The Of static load was carried by the ore pass walls and the limbers adjacent to the chute.

An ore pass is a vertical or near-vertical opening, which is created during underground mining operations to transfer materials. It is designed based on the gravitational force between different ground levels, in order to provide a convenient material handling system and reduce haulage distances.
Loading chutes are constructed in various ways and consist essentially of a framework of timber, steel, or concrete with gates or other means provided for …
Ore pass section inclination Ore pass inclination in Quebec operations varies between 45° and 90°, with an average inclination of 70°, Figure 2. Interviewed mine personnel provided contradictory justifi-cation for the choice of inclination and its desired effect on material flow. The choice for a particular inclination is
Thus, it is common practice to drive an ore-pass raise at 50° to 60° for 50, 75, or 100 feet and then "knuckle back" on a slope in the opposite direction. This often assists materially in reducing wear on ore-pass linings and preventing breakage of chutes and gates.
