| Abstract: |
Slip instability and tensor instability are two kinds of failure modes of cemented waste rock backfills. In order to simulate the creep characteristics of cemented waste rock backfills, PFC was carried out. The results show that: rocks inside the models will have displacement under load. The expansion is caused by large lateral displacement of the rocks. A non-stationary creep model of cemented waste rock backfills was established based on the results of simulation. This model can be used to describe the whole creep characteristics of cemented waste rock backfills better. |
