  • Rockfall Protection in Mining - FMDRCZ

    Rockfall systems in the environment are used as a means of protecting the ’s assets which include employees and plant. The word “system” correctly embraces the different structural components that should be considered when facing a rockfall problem. Different types of systems are available, and a key distinction should be made between active

  • Highwall concerns : Pit & Quarry

     · Control of the rock fall reduces its energy and contains the rocks to a catchment area where they can be collected and removed in a safe manner. Minimal maintenance is required if designed properly. The type of material used for the mesh design should be scrutinized to make sure it can manage potential rock falls without tearing and creating gaps in the system
