  • The main reason of the pollution caused by soils and tailings located at discussed mines is heavy metals and AMD(acid mine drainage). Human health is affected by these pollutants which are spreaded from the abandoned mines. In this study, we try a mathematical approach to predict the pollution level of heavy metals caused by the surrounding soils of abandoned mines. The new approach is established with the correlation between the distance and pH, ORP. The change of pH and ORP can be described by the rate of initial values to experimental values. We demonstrate a realistic possibility of the mathematical approach to assess an environmental impact from disused mines cause the rate range is 0.95 to 1.03 for 60 days. Therefore our proposed approach will be useful as a few promising method for the management of heavy metals in many mines.
