4. PARAMETERS OF CHUTE DESIGN. The following parameters are used to differentiate between good and bad designs. In the future, the aim is to produce design guidelines for use as an office standard. Chute Angles. The angle of repose for dry, runofmine gold ore is generally taken to be 38.
From wet sticky iron ore fines to dry and dusty coke, we have the experience, knowledge and technology necessary to design transfer chute systems capable of continuous reliable performance. Key to successful transfer chute design is a thorough understanding of the properties and characteristics of the bulk material being transferred.

Extremely Sticky Iron Ore application Old Chute • Handling very sticky Maramamba iron ore fines material. • Old chute consists of a hanging chain design due to very cohesive and adhesive ore properties. • Old chute required ongoing (once per shift) complete washdown to address blockages.
Ore passes are simply vertical or inclined openings for transfer of broken ore to the haulage system. They may be raises in the ore or in the walls of the deposit or timbered openings through filled stopes and, as previously stated, usually terminate at the bottom in some form of loading chute. They must be steep enough to insure that the ore will run freely and usually are inclined at angles ...
When the ore body is more or less horizontal, various forms of room and pillar stoping, cut and fill, or longwall mining can take place. In steeplydipping ore bodies, such as lodes of tin, the stopes become long narrow nearvertical spaces, which, if one reaches the surface is known as a gunnis or coffen. A common method of mining such ...
Sep 20, 2010· 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 troublefree.
Chute design has been the subject of considerable research, a selection of references being included at the end of this paper [129]. However, it is often the case that the influence of the flow properties of the bulk solid and the dynamics of the material flow are given too little attention. The
