The Surface Mining Control and Reclamation Act of 1977 delegated that, as part of the mine permitting process, mining operations must evaluate probable hydrologic consequences and regulatory authorities must review these evaluations and perform cumulative hydrologic impact assessments for mining operations. The original OSM model has been significantly modified to increase its capabilities and allow considerable flexibility in data input and output. The model can simulate effects from multiple pumping/injection wells and multiple mining/reclamation operations with variable schedules, within layered and dipping strata. Hydrologic influences of surface water-ground water interaction, leakage between aquifer units and evapotranspiration are also taken into account. Output from the model utilizes various graphics routines which provide quick and efficient means of evaluating hydrologic effects resulting from mining, and may be used directly in the preparation of mine plan reports.
