ROCKFALL PROTECTION

KEY TAKEAWAYS

Rockfall problems should be addressed with a targeted approach, as each specific site requires an analysis of its particular natural and anthropogenic risks.

Elongation of Steelgrid HR is in the range of 5-7% compared with 16-23% for double twist meshes depending on mesh/wire combinations.

When designing rockfall solutions for open-pit operations, Maccaferri takes into due account a series of parameters, including subsurface geology, slope morphology, hydro-meteorological conditions, vegetation and loads from equipment, among others.

PROTECTING QUARRIES FROM ROCKFALLS Any quarry’s safety and operations may be threatened by rockfall hazards, which can sometimes cause serious disruptions to mine productivity. This may result in significant financial losses. With more than 120 years’ worldwide experience, Maccaferri offers a wide range of rockfall protection systems to help open-pit operations stabilise rock faces, resulting in increased safety and reduced risks and costs, writes Munesu Shoko .
