在研究影响费克扩散定律各因素的基础上，经过推导，得到了粉尘扩散系数的表达式．分析表达式得到了影响矿井粉尘扩散系数的主要因素，并研究了影响因素对于粉尘扩散系数和粉尘浓度的作用规律．研究结果表明：矿井粉尘扩散系数受温度和粉尘粒径的影响，温度影响较小．粒径越小，扩散系数越大，粉尘扩散越快，粒径小于1μm的粉尘这一趋势更为明显．研究对于矿井采取粉尘防治措施具有一定的参考价值．

Based on the each influent factor of Fick diffusion law, through the derivation, the expression formulation of diffusion coefficient is obtained. According to the analysis of formulation, the main influence factor for coal mine dust diffusion coefficient is obtained, and the impact law of influence factor for dust diffusion coefficient and dust concentration is studied. The research results show as follows： the dust diffusion coefficient is influenced by temperature and dust size, and the temperature is relative smaller. The smaller the dust size, the bigger dust diffusion coefficient becomes, the faster the dust diffuses, and the tendency is more obvious for the dust size less than 1 μm. The research has referential value for dust preventive treatment of coal mine.
