The stabilisation of rock faces, cuttings and slopes utilises a wide variety of techniques such as the application of rock bolts or dowels. To ensure a practical design and ongoing safety of these slopes and cuttings, a sound knowledge of geological structure, rock mechanics and hydro geology must be applied when selecting the best solution.

ROFRAQ: A statistics-based empirical method for assessing ...

Rockfall Risk Assessment for Quarries (ROFRAQ) is an empirical method for assessing rockfall hazard in hard rock quarries and open pit mines in temperate climate regions. The method is based on the observation that a rockfall-related accident in a mining environment typically occurs as a consequence of five sequential events, as follows:

Abstract. Large, deep open-pit mining projects lead to rockfall, which becomes an engineering hazard second only to slope stability. The V shaped gully (V-gully) method introduced here was shown to have a significant effect on preventing rockfall through reduction of kinetic energy and rainfall discharge.
