Blasting dust is the main source of atmospheric pollution in deep, sunken open-pit mines (DSOMs), which affects seriously the normal work and production in the mines. Here, the influencing factors and a diffusion model with regard to blasting dust diffusion were investigated and proposed in a representative mine. Dimensional analysis and multiple nonlinear regression analysis were applied to establish a mathematical model of the blasting dust diffusion. A high multiple correlation coefficient of 91.4% was obtained, indicating a highly reliable model. This study provides a theoretical basis for rationally arranging production and avoiding air pollution in the DSOMs.
爆破粉尘是深部凹陷露天矿大气污染的主要来源，严重影响矿山的正常作业和生产。在此，针对某典型矿山，研究并提出了爆破粉尘扩散的影响因素及扩散模型。采用量纲分析和多元非线性回归分析方法建立了爆破粉尘扩散的数学模型。得到了高达91.4%的多重相关系数，表明该模型具有高度可靠性。本研究为深部凹陷露天矿合理安排生产、避免空气污染提供了理论依据。
