Acid/Toxic Drainage and Seeps Identification
During the removal of overburden, toxic or acid-forming materials are often encountered and must be segregated and isolated during mining so as not to be a detriment to successful revegetation, spoil disposal areas, affect the stability of backfill or contribute to acid mine drainage (AMD). It is not always apparent from an on-the-ground inspection that AMD is present or it may be in a location that is not easily accessed. (VIP 4) High resolution multispectral satellite imagery can help identify the location and extent of AMD on a mine site.
