摘　　要：为研究煤尘组成与水润湿性能关系,对13种不同变质程度的煤尘进行了工业分析和元素分析,系统研究了煤尘的基础特性。采用毛细管上向渗透法测定煤尘对水的吸湿量,分析了13种煤尘的煤质组成与煤尘对水的吸湿量(润湿性)之间的关系。根据线性和非线性回归的方法,建立了煤尘的煤质组成与水之间润湿性的最佳回归方程,确定了影响煤尘对水吸湿量(润湿性)最显著的煤质因素。In order to investigate the relationship between coal dust composition and water wettability. The proximate analysis and ultimate analysis of 13 kinds of coal dust with different metamorphic degree are carried out. The moisture absorption of coal dust to water was measured by capillary upward infiltration method, and the relationship between the composition of 13 kinds of coal dust and the amount of moisture absorption （wettability） of coal dust is analyzed. According to the linear and nonlinear regression method, the best regression equation between the coal quality and the water wettability is established, and the most important factors affecting the moisture absorption （wettability） of coal dust were determined.
