尾矿风蚀是一种空气污染问题，但研究还不够深入。事实上，目前还没有准确的方法来预测尾矿库的逸散性粉尘排放强度。本文报道了基于物理原理的风蚀模型的发展。与大多数针对农田或沙丘开发的风蚀模型不同，该模型考虑了风速的波动。该模型旨在预测易受风蚀的平坦尾矿库每小时的粉尘排放率，用于空气质量建模。利用风洞数据和现场试验对模型进行了评价，验证了该模型对工业破碎物料的有效性。作者在智利的Mantos Blancos矿进行了现场实验，进一步验证了该模型。
The wind erosion of mine tailings is an air pollution concern that has not been investigated thoroughly. Indeed, there is no accurate method to predict fugitive dust emission strength of tailings dumps. This paper reports on the development of a wind erosion model based on the principles of physics. Unlike most wind erosion models developed for agricultural lands or sand dunes, this model takes into account the fluctuations in wind velocity. The model was designed to predict hourly dust emission rate of flat tailings dumps prone to wind erosion for air quality modelling purposes. The model was evaluated using wind tunnel data and field experiments which confirmed the validity of the model for crushed industrial materials. The model was further validated with field experiments undertaken by the authors at the Mantos Blancos mine in Chile.
