【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。
[Abstract]:In order to study the relationship between the composition of coal dust and the wettability of water, 13 kinds of coal dust with different degrees of metamorphism were analyzed by industrial analysis and elemental analysis, and the basic characteristics of coal dust were systematically studied. The moisture absorption of coal dust to water was determined by capillary upward permeation method. The relationship between the coal composition of 13 kinds of coal dust and the moisture absorption (wettability) of coal dust to water was analyzed. According to the linear and nonlinear regression method, the best regression equation between the coal composition of coal dust and the wettability of water was established, and the most significant factors affecting the moisture absorption (wettability) of coal dust to water were determined.
