<p>Although some of the prevalence of openpit production scheduling software can be explained by the predominance of openpit mining throughout the world, other factors have led to a lag in corresponding underground software. We explain mathematically why underground ...

Physical testing of rock support for rockbursting conditions has been carried out for over 40 years. A review of this testing shows that it has been mostly component–based, rather than actually testing support systems. Further, it is concluded that none of ...

The geometry and morphology of a set of low-angle fractures around a stope in a deep Witwatersrand gold mine are explained in terms of extension fractures forming under variable conditions of stress. Primary extension fractures (E1) form some distance ahead ...

Many states allow construction of landfills over previously mined areas. However, mitigation of the underground mines by filling or removal is often required prior to landfill construction. A settlement analysis for the proposed vertical expansion of a residual ...

<p>The Department of Mining Engineering at Queen&rsquo;s University conducted a study of backfill practices in underground mines across Canada to assess the current state of backfill usage and to overview potential hazards associated with backfill practice, ...

This paper presents the preliminary results of a laboratory testing program aimed at assessing the impact energy dissipation capability of a new rock bolt. The results represent the most up to date findings at this current time. In situ field tests are still ...

An effective prototype face support system to minimise rockfalls in rockfall-prone mines was developed and patented during a project sponsored by the Mine Health and Safety Council (MHSC). An experimental development model (XDM) roof support unit was developed ...

It was found that current mine layouts have been successful in providing support to the overburden, while a small number of isolated pillar failures were observed. The stable pillar layouts and failed pillars were plotted on a chart that demonstrates the relationship ...

The paper describes an R&amp; D programme carried out on Cempak, a proposed stope support system for deep, tabular, hard rock gold and platinum mines; which looks in particular into the issue of convergence after attainment of peak load. Cempak fundamentally ...
