ABSTRACT
ABSTRACT: Numerical models of hydrogeochemical processes are commonly used prior to mine startup or expansion to forecast conditions at closure. While forecasting is an important use of numerical models prior to mine startup and for assessments of mine expansion, the models can also be restructured as investigatory tools for guiding decisions about the potential efficacy of implementing various reclamation options prior to closure. In fact, models developed and refined during mine operation may be expected to be more reliable than those used for pre-mine forecasting because they are based on updated conceptual models and can incorporate data measured during mining that are characteristic of important site-specific hydrogeochemical processes.
