or freeing ore pass chutes and structural failures of control gates and ore pass walls. Researchers at the Spokane Research Laboratory of the National Institute for Occupational Safety and Health are investigating these hazards and developing methods to improve safety during transport of ore and waste. Particle flow analysis methods were used to
May 24, 2014· Ore pass is a vertical or nearvertical opening created during underground mining operation to transfer materials. It is designed based on the gravitational force between different ground levels to provide convenient material handling system and reduce haulage distances.
Gravity usually is employed wherever possible to move broken ore from stopes to the haulage levels, and orepasses from the stopes terminate at the bottom in chutes, by means of which the flow of the ore into cars or onto conveyors can be controlled.
Variant Mining Technologies is calling it the biggest ore chute in the world. The Sudburybased company said it built the chute for Rio Tinto''s Oyu Tolgoi mine— a combined underground and open pit copper mine in the Gobi Desert. A chute is used to safely control the flow of rock from an ore pass to.
Variant Mining Technologies manufactures underground mining chutes, arc gate chutes, inline loading chutes, vibratory feeders and measuring boxes specifically designed for easy assembly and installation for the safe, reliable and costeffective transportation of material in the ore flow process. Variant Mining Technologies can provide the products, knowledge and support to make your mining ...

Since vexatious and costly delays and broken chutes often result from "hung" ore passes, it is poor economy to restrict their size. It is customary to carry a manway along one side of the ore pass as a separate compartment of a twocompartment raise, and access to points where the ore pass becomes blocked may be had from the manway.

Conveyor Chute Lining. ASGCO''s Chute Linings and Skirt Liners are designed to be an integral part of a conveyor system. Our preengineered chute lining protects and cushions the chute from the material being handled; Skirt Liners prevents fugitive materials from escaping and .
ore chute[′ȯr ‚shüt] (mining engineering) An inclined passage for the transfer of ore to a lower level. Ore Chute a vertical or inclined mining excavation for transporting ore and other useful minerals by force of gravity. Hatch devices or feeders are installed in the lower portions of ore chutes for loading ore into hauling vessels or onto ...
AbstractOre and waste rock flow through ore passes can be improved by reducing contributing factors to formation of hangups and by selection of the most suitable methods of bringing formed arches down. The prevailing factors contributing to the formation of hangups are consolidation and compaction of material and constriction in the ore passes.
Numerical investigations of ore pass hangup phenomena. ... Another potential source of blockage is the accumulation of fine or "sticky" material in or near the chute, on the ore pass floor. This further reduces the effective cross sectional area and can result in more blockages. ... Ferguson G. Ore pass design guidelines. Report to Mining ...
Analysis of Hangups and Structural Failure 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
Spillminator Chute criteria. We offer SideWall Chutes, HangingWall Chutes, and Belt Feeders. In accordance with SANS specification 0208, the Chute is designed for a nominal design pressure of 840 kPa in platinum mines and 600kPa in gold mines. 840 kPa is equivalent to a 30m ore pass filled with UG2 slurry (hydrostatic head).
Water inflow into the ore pass should be avoided. Ratholing. This can be controlled by modifying the size of the chute or hole drawing from the ore pass. Its a subject for detailed engineering stage. Wear Based on a review of ore pass literature, operators differ in opinion as to whether wear is reduced by operating the ore pass empty or full.
