FEP Effects
Description of FEP Effects
Exploratory drilling (see FEP 8). Perforation of the host rock. Excavation of deep access shafts and drifts, leading to changes in hydraulic properties and/or creation of preferential pathways. Removal of potentially large amounts of material at depth, leading to changes in stress field and stability; deformation of overlying rocks; possibly changes in geochemistry.
