Some research aspects on Australian waste disposal

British Columbia Mine Reclamation Symposium

Some research aspects on Australian waste disposal Chappell, Brian A.

Abstract

Rock waste densities achieved in the construction of the embankments are a function of the manner in which the rock is placed and compacted. Just dumping the rock achieves low densities varying from 0.9 to 1.2 t/m³. This results in large deformations in the subsequent behaviour of the waste dump. Because of the anisotropies induced in the rock dump from both the placement and compaction techniques these deformations instigate major load arching characteristics of the embankment loads. The anisotropic rotational effects redistribute the embankment loads on to the valley abutments. The formation of the valley sheet joints generally occur in the regions where the embankment loads are arched onto the valley abutments. Of consequence these aspects of anisotropy, arching and valley sheet joints, require careful consideration.
