摘　　要：分析了水煤浆管道输送过程中的浆体流动规律及煤粉颗粒的运动情况。通过对煤粉颗粒和管壁的摩擦过程分析,推导了水煤浆输送管道的管壁磨损量计算方法。计算表明:水煤浆对管壁的磨损很小。这进一步证明了建立长距离水煤浆管道输送系统的可行性。通过对管道磨损过程的解析,提出了减少磨损的具体措施。The flow characteristics of Coal-Water Slurry (CWS) and the movement of coal powder in the pipeline transportation of CWS are analysed. Then, the calculation method of CWS pipe wearing has been got by analysing the rub process of coal powder with inner surface of pipe. It has been proved by the calculation results that the pipe wearing is very slight in proof of the feisibility of long distance pipeline transportation of CWS. Detailed measures are also analysed to reduce pipe wearing of CWS.
