  • 2.1 Introduction to Quarries — University of Leicester

    Some quarries produce rock which is extracted or cut into large blocks (e.g. Portland limestone) or to be cut into slices to form “cladding” on the front of buildings (e.g. granite or marble). In these quarries there is unlikely to be a blasting, and certainly no crushing and screening, so these operations have not been considered in the EE-Quarry project. The processes used in quarrying ...
