摘　　要：为了探究煤岩矿物成分与润湿性的关系,选取贵州省织金、普安、六盘水3个区块地下不同深度煤样以及露头煤块,利用X射线衍射技术、JC2000DM接触角测量仪等仪器,分析了不同煤样矿物含量以及非晶质含量与接触角之间的关系,遴选出了1套复合表面活性剂,其能够有效增强煤岩疏水性。In order to explore the relationship between the mineral composition and wettability of coal and rock, the coal samples and outcrop coal at different depth in three areas of Zhijin, Pu＇ an and Liupanshui in Guizhou province were selected, and the relationship among the mineral content of different coal samples, the amorphous content and the contact angle was analyzed by X-rays diffraction and JC2000DM contact angle measuring instrument. And also selected a set of complex surfaetants to enhance the hydrophobicity of coal.
