Quarrying - an overview ScienceDirect Topics

Quarrying involves the fracture of large fragments from rock beds largely due to the process of discontinuous rock-mass failure. Preglacial weathering can also weaken rocks and assists the quarrying process. Additionally, freeze-thaw processes may be active beneath glacier margins where heat can be evacuated from the bed.
