Influence of Lateral Loading on Compaction Characteristics of Crushed Waste Rock Used for Backfilling

open access: yesMinerals (Basel, Switzerland), 2018
Crushed waste rock can be used as backfill in goafs to allow re-use of otherwise solid waste and to control surface subsidence. If a certain lateral stress is applied to crushed waste rocks beforehand, they are densified.

Investigation of Lateral Pressure at Small Compaction Forces

Powder Metallurgy and Metal Ceramics, 1967
1. An installation has been developed for measuring the lateral pressure of powders at small compaction pressures. It was established that, at low compaction pressures (2–42.5 daN/cm2), the coefficient of lateral pressure is constant and practically independent of powder particle size. 2.
