The objective in this experimental programme was to monitor microseismic activity at field scale in the same way that acoustic emission (AE) are monitored at sample scale, noting that the temporal variation of the AE level (or cumulated level) appears to be ...

Deformation of underground salt, trona and potash mines is generally time dependent, providing for gradual adjustment of strata to mining induced stresses. Time dependence can allow for higher extraction ratios provided eventual failure can be tolerated. However, ...
