The occurrence of acid mine drainage could also be explained with the phenomenon of mining under the surface. Sub-surface mining often progresses below the water table, so water must be constantly pumped out of the mine in order to prevent flooding. When a mine is abandoned, the ,pumping, ceases, and water floods the mine.

Due to tidal ,pumping,, the recirculated seawater drains out during ebb tides and seeps into the seabed sediments during flood tides. Simultaneously, the hydrostatic pressure is lowered and the hydraulic gradient between seawater and groundwater increases, which leads to a large SGD flux at low tide.
