凌赵输煤管道运行参数剖析

ANALYSIS OF THE OPERATING PARAMETERS OF THE COAL TRANSPOTATION PIPELINE LEADING FROM XIAOLINGHE HYDROMINE TO ZHAOJIATUN MINE WASHERY

提出了南票矿务局小凌河矿至赵家屯矿区选煤厂长为１１ｋｍ，水采浓缩煤浆管道输送系统安全可靠、经济高效运行的基本条件参数（悬浮性、均匀性、稳定性指标）和主要技术参数（临界流速、摩阻损失）及其计算方法，可供我国开发高浓度、长距离、大运量输煤管道设计参考．

The basic conditional parameters (suspendability,consistency and stability)and main technical parameters(critical velocity and friction loss) and their calculation methods for ensuring safety, reliable, ecnomic and highefficiency operation of the 11 km pipeline leading form the Xiaolinghe Hydromine,Nanpiao Mining Administration to Zhaojiatun Mine Washery for transporting thickened coal slurry is described.These may serve as a base for reference in designing highdensity, longdistance and bulk coal transportation pipeline in China.
