Mining operation of open cut mines has serious impacts on surrounding environment. Therefore, an appropriate rehabilitation program has to be taken into consideration. Soil erosion is one of the major environmental problems in open-cut mines in tropical regions. The soil erosion leads to unsuccessful rehabilitation due to topsoil losses. In order to succeed rehabilitation, the condition of soil erosion in the rehabilitation area has to be predicted accurately. As one of an efficient method for prediction of soil loss, Universal Soil Loss Equation (USLE) is the most widely used method of predicting soil loss in forestry. However, when considering the application of this equation in rehabilitation area, a sufficient consideration is needed because the condition of these areas is very different from that of forestry. This paper describes the reliability to predict soil erosion in rehabilitation area by means of USLE, and discusses the several considerations on soil erosion.
