| 摘 要： | 以山东某选煤厂的难沉降煤泥水为研究对象，利用现代分析测试手段，分析难沉降煤泥水的水质特性、矿物组成、粒度组成、表面电性等。结果表明导致煤泥水难沉降的主要原因是煤泥水中粘土矿物含量较高，泥化现象严重，颗粒粒度小，表面带有很强的负电荷，具有胶体稳定特性，从而导致其难以沉降。

| Abstract: | Discuss the difficult settling coal slurry of a coal preparation plantp in Shandong province. Different kinds of detection means were used to determine the water quality, mineral compositions, particle size distributions and surface electric properties. The results show that the primary factors which influence the sedimentation are the high clay minerals contents, the small particles with strong negative charges and the colloid stable system. |

| Keywords: | coal slurry water quality particle size distribution surface electric property |
