Hydrogeologic Conceptual Site Model Development – Tools and Lessons Learned

Development of a representative hydrogeologic conceptual site model (CSM) is an iterative process that begins during mine exploration and permitting and continues during operations and mine closure and reclamation. Hydrogeologic data sources, field data collection methods, and analysis methods will be reviewed to efficiently characterize groundwater flow systems including effects related to mine dewatering, infiltration, and water management. Accurate characterization of geologic structures, preferential flow pathways or barriers to flow, recharge and discharge areas, and groundwater interaction with mined materials (ore, waste rock, and overburden) can streamline mine operations and may allow alternative closure and reclamation scenarios.
