<p>Testing of axial load transfer of various Australian cable bolts has been conducted in overseas laboratories within the last two years (Thomas, 2012). The comparative laboratory testing determined that nutcaged cables and indented wire cables provide stiffer ...

<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 ...

Underground stone mines in the United States make use of the room-and-pillar method of mining. A prerequisite for a safe working environment is that the pillars should adequately support the overburden and the pillar ribs and rooms should remain stable during ...

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>The intact rock strength of a rock mass has been determined by several different means in the context of research for slope stability assessment. The intact rock strength was determined with unconfined compressive strength testing, Schmidt hammer, Equotip, ...

<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 ...
