AMD: Remining coal - Lehigh University

Instead of contaminant concentration (e.g., mg/L) levels and pH of the effluent, prediction of contaminant load (e.g., lbs/day or kg/day) levels become the primary objective for remining mine drainage prediction. Discharge flow rate is used to determine contaminant load and becomes a primary determinant of the reviewed effluent standard.

Technique for predicting ground-water discharge to surface ...

Changes in seepage flux and head (groundwater level) from groundwater drainage into a surface coal mine can be predicted by a technique that considers drainage from the unsaturated zone. The user applies site-specific data to precalculated head and seepage-flux profiles.

Most active coal mines in the region discharge at higher SC levels (commonly > 1000 μS cm −1) during and immediately after active operations and elevated SC release continues for extended periods of time beyond mine closure (Evans et al., 2014, Pond et al., 2014). Thus, a clear need has emerged to develop prediction approaches to identify ...
