摘　　要：煤尘的凝并特性是影响喷雾降尘效率的重要因素。选取不同产地的煤为实验样品,进行工业分析和元素分析,对其结构参数、含氧官能团含量及其在溶液中的凝并性能进行测定;利用SPSS19.0软件,采用多元线性逐步回归分析法研究煤尘的上述参数对煤尘凝并特性的影响。研究表明:影响煤尘在水中凝并特性的主要因素是煤中水分(Mad)、挥发分(Vad)、煤表面酚羟基官能团含量(phenolic hydroxyl,PhOH)以及芳碳率(FA)。最优回归方程的复相关系数为0.983,线性关系显著,拟合优度较高,煤尘凝并特性的研究对有针对性地开发矿井降尘剂具有重要指导作用。The coagulation characteristic of coal dust is one of the important factors affecting the efficiency of dust suppression by praying.Based on coal samples selected from different regions,this research measured their structure parameters,their content of oxygen containing functional groups and their coagulation performance in solution through industrial analysis and element analysis.With the help of SPSS19.0and multiple linear stepwise regression analysis,the parameters＇ effect on the coagulation of coal dust was studied.The research shows that the content of moisture（Mad）,volatile matter（Vad）,and the content of phenolic hydroxyl groups on the surface and aromatic carbon rate（FA）are the major factors affecting coal dust＇s coagulation in water.The complex correlation coefficient for optimal regression equation is 0.983,showing significant linear relationship and higher goodness-of-fit.The study of coal dust＇s coagulation plays an important guiding role in the development of dust suppressant in coal mines.
