Abstract
Abstract
| In Arctic surface mines, frozen ground adds to the complexity of slope stability analysis. The seasonal temperature change may thaw permafrost, and this thawed ground is often unstable. A computer program, GEODYNE, was used to simulate the movement of the thaw front in bare and insulated permafrost slopes. The simulation shows that the insulation can be used on mine slopes to prevent thawing. |
