Study on method for minimizing soil erosion in open-cut mines in tropical regions
Soil erosion is one of the major environmental problems in open-cut mines in tropical regions.It causes negative impacts including the removal of nutrient rich topsoil, destroy aquatic habitat, dam and pond siltation, clog river by deposition of sediment, and water pollution in the rehabilitation process.Therefore, it is important to predict soil erosion in advance and establish the proper process to minimize the phenomenon for the success of rehabilitation in the disturbed land.Soil texture is an important factor to affect soil erosion.In this study, artificial rainfall experiment in laboratory scale were conducted to clarify the mechanism of soil erosion and to discuss the method for minimizing soil erosion.From a series of discussions, the importance of selecting prevention method considering type of soil in order to minimize soil erosion was indicated because the prevention effect on soil erosion was different depending on type of soil.This paper describes the effect of soilcomposition on soil erosion and the effective countermeasures to minimize soil erosion in the rehabilitation area.
