| Rockfalls are a relevant hazard in quarrying and open-pit mining as well as in roads with rock cuts. The Spanish Association of Aggregate Producers reported that the most common cause of fatalities in their quarries comes from rockfalls. With the aim of having available methods to quantify this phenomenon in mining, the existing rockfall hazard rating systems for roads such as the RHRS and the RHRON were reviewed to conclude that these methods could not be applied to the working conditions of an open pit mine or a quarry. This lead to develop a new technique able to assess rockfall in quarries and open pit mines, named ROFRAQ based on empirical observations and a probabilistic approach that assumes that an accident occurs as a result of a sequence of events. Different events are rated, and the product of these ratings represents an estimate of the probability of accidents due to rockfalls. In this paper will be presented two particular case studies to quantify the risk of rockfall in mining operations with this new developed method, to find out that a low risk exists, and that simple protective measures can contribute to a safer environment. | |
