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.
