膏体充填技术由于其在安全、环保、高效等方面的优势,逐渐成为充填法重要的发展方向,而膏体的管道输送是整个系统中的关键环节. 壁面滑移现象存在于膏体流动过程中,但是其机理并不明确,国内外对于膏体滑移流动行为并没有进行过深入研究,探明其规律对于有效减小膏体管道输送阻力和降低能耗具有十分重要的现实意义. 详细介绍了浆体管道壁面滑移研究现状,讨论了管道滑移效应的影响因素,在此基础上,提出膏体管道滑移研究趋势.

Paste filling technology has gradually become an important development direction of filling method because of its advantages in safety,environment protection and high efficiency and other aspects,and the paste conveying pipeline is the key link in the system. The phenomenon of wall slip exist in the process of paste flow,but its mechanism is not clear,and the research for behavior of paste slip flow is not conducted deeply both at home and abroad. It is of great practical significance to explore its law for the sake of reducing resistance of paste pipeline transportation efficiently and energy consumption. The re-search status of wall slip in slurry pipeline is introduced,and the influence factors of slip effect in pipeline are discussed. On this basis,the trend of research on wall slip of paste is put forward.
