摘要
我国露天矿粉尘治理形势依然严峻,文章阐述了混沌学及分形学的研究现状及发展趋势,探究了混沌分形理论应用于矿山粉尘研究的进展,最后讨论利用混沌分形理论建立粉尘分形扩散方程和构建露天矿立体空间模型。粉尘粒子具有很好的分形特征,其分布可用分数维来描述,以此得出露天矿作业中粉尘的分布特征和扩散规律,能为露天矿的防降尘工作提供理论与技术支持。
The situation of dust control in open-pit mines in China is still grim.This paper expounds the research status and development trend of chaos and fractals,discusses the progress of chaotic fractal theory in the application of mine dust,and finally discusses the use of chaotic fractal theory to establish dust fractal diffusion equation and construct open-pit mine three-dimensional space model.Dust particles have good fractal characteristics,and their distribution can be described by fractal dimension,so as to obtain the distribution characteristics and diffusion law of dust in open-pit mine operation,which can provide theoretical and technical support for dust prevention and reduction in open-pit mine.
