ABSTRACT
Rockfall is one of the most critical geological events that can affect quarrying activities. Nevertheless, few tools are currently available to help designers and managers correctly define the risk conditions and quantify the advantages, in terms of workers' safety and quarry management, that can be obtained using suitable prevention devices. For this reason it is necessary to evaluate the various parameters that are involved, and to define the most important and which have the greatest influence on rock-fall phenomena, taking into account the Prevention through Design approach. A risk evaluation system which is able to support decision makers in the critical rockfall risk assessment phase, and offer decision makers the updated information that is necessary for a continuous and dynamic operation design during exploitation activities is here presented and discussed.

QuaRRI - nowa metodologia analizy ryzyka obrywania się skał i jego zarządzania w kamieniołomach

Obrywanie się skał jest jednym z najbardziej niebezpiecznych zjawisk geologicznych zachodzących przy wydobywaniu kamienia. Obecnie zarządzający i projektanci dysponują szeregiem środków, które pomagają precyzyjnie określić stopień ryzyka, jednocześnie podnosząc bezpieczeństwo pracy zarówno kamieniarzy/pracowników bezpośrednio wydobywających kamień jak i kadry kierowniczej. Środki te mają przede wszystkim funkcję prewencyjną. Dlatego też sprawą pierwszej wagi jest określenie różnorodnych parametrów specyficznych dla danych warunków oraz precyzyjne zdefiniowanie, które z nich są najbardziej istotne w przypadku obrywania się skał poprzez stosowanie metody Zapobieganie poprzez Projektowanie (Prevention through Design-PtD). Zaprezentowany tutaj system oceny ryzyka, na którym mogą się oprzeć decydenci w najbardziej krytycznej fazie oszacowania niebezpieczeństwa przy oderwaniu się skały, oferuje również aktualne informacje niezbędne do prowadzenia prac przy eksploatacji kamieniołomów przy równoczesnym zminimalizowaniu ryzyka.
