Description

Lijuan Su and co-authors describe a 2024 study of a mine fill made from burnt waste ash. The fill, set with alkali and slag, must bear load for years in old mine voids. Slow squash under steady load, called creep, can threaten the rock above if it grows too much.

The team ran creep tests at five load levels, then under three way loads that mimic the mine setting. Curves fell into three shapes, from slowing creep to a late fast stage. Total creep strain stayed under one percent, much like soft rock. Most of the shift came at first loading. Gel in the fill bound grains and slowed the late fast stage. A math model with a special dashpot fit the full curve set.
