PBE-News

A material''s angle of repose is defined as the angle of heap formed when an unconsolidated material is poured freely onto a horizontal surface. This is called the static angle of repose.The angle of repose changes when the pour height changes. Similarly, the angle of repose for a material can change when a material is poured onto a moving surface because of the agitation caused by the movement.

Angle of Repose

Angle of Repose is a 1971 novel by Wallace Stegner about a wheelchair-using historian, Lyman Ward, who has lost connection with his son and living family and decides to write about his frontier-era grandparents. It won the Pulitzer Prize for Fiction in 1972. The novel is directly based on the letters of Mary Hallock Foote, later published as A Victorian Gentlewoman in the Far West.

Sub-level open stoping

Ore bodies that are ideal for sublevel stoping are very tall and have a medium to narrow width, but can have an extensive length. The ideal width of the orebody should be greater than 6 meters but less than 30 meters. Most of the time this type of orebody has a dip greater than the angle of repose of the ore, or steep enough so that the ore can ...
