The effect of thermal cycles on limestone mechanical degradation

 · The Rock Mechanics convention is used (positive strain means extension). In all the cases, an accumulation of deformation can be observed as the number of cycles increases. Accumulation is in extension for samples B1, B3 and CV4 and seems to stabilize consistently around value close to 3 × 10 −4 and 6 × 10 −4 for the axial and radial strain, respectively.

The Implementation of Rock Mechanics Into a Multiple Level …

The efforts to implement rock mechanics were re-focused as Level 2 approached its mineable limit and the initial attempt to drive a decline to Level 3 was unsuccessful. A second decline site was selected based on inter burden stability, a consistent shale parting for the Level 3 back horizon, results from numerical models of the immediate back and multiple level interactions, …
