<p style="text-align: justify;">The LKAB Malmberget Mine is mined using sublevel caving. This mining method is cost-effective but results in successive caving of the host rock and mining-induced ground deformations. Consequently, re-locations of residential ...

The geologically neutral term bimrocks (block-in-matrix rocks) includes melanges, fault rocks, lahars, weathered rocks and other geologically complex mixtures of strong rock blocks embedded within weaker matrix rocks. Bimrocks have mechanical contrast between ...

<p>Whether the aim be to prevent collapse or to promote it, rock strength is an important factor in many practical problems of rock mechanics. The property of &lsquo;strength&rsquo; of a rock derives, as with all solids, from various types of inter-atomic ...

<p>Observations of pillar failures in Canadian hard-rock mines indicate that the dominant mode of failure is progressive slabbing and spalling. Empirical formulas developed for the stability of hard-rock pillars suggest that the pillar strength is directly ...
