ANGLE OF REPOSE EVERYWHERE

Angle of Repose it Means Business!
In agriculture and mining, there are many phenomena related to angle of repose,
especially those concerning storage, such as grains and coal. To work out the volume
of a pile of particles (e.g. wheat), the angle of repose is most often used. In the
mining industry, angle of repose is always a concern in storage capacity, mine tailings
dumping, and excavation work.
||The volume of a conical pile can be worked out by the radius and the
angle of repose of the grains.|
|The knowledge of angle of repose helps in the design of the conical top
of the storage facilities for grains, such as this one near Narrabri.
In the mining and construction industry, volume of the storage can also be calculated
using the angle of repose. Angle of repose is also a major concern in occupational
health and safety. The maintenance of a stable slope is essential in both mine tailings
dumping and roadwork. If the slope is too steep, the chances of a landslide occurring
