Combining with the related transportation theory of Engineering Fluid Mechanics and for deep level pipelines, the classified tailing slurry under different stowing gradient conditions with full pipeline flowing characteristics of transportation is numerically simulated based on the Fluent software. It is shown that compared with the free fall system, the full pipeline flowing system greatly reduces the impact abrasion and pressure to the pipeline. The outlet pressure of the classified tailing full pipeline flowing conveying system increases with the stowing gradient, and the total pressure remains constant; the diameter has a great influence on the hydraulic slope of the filling slurry, the measures of adjusting the pipeline are beneficial to the full pipeline flowing transportation in deep mines; when the pipe length-backfilling depth ratio N=6.0, the pressure loss of the classified tailings reaches the minimum of 0.247 MPa., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null,

articleAbstract=针对某矿山分级尾砂充填料浆自由下落对管道产生严重磨损的现状，引入分级尾砂料浆满管流输送技术。基于Fluent软件，并结合运用工程流体力学和深井管道输送相关理论，对不同充填倍线条件下的分级尾砂料浆满管流输送的工作特性进行了数值分析。结果表明，满管流输送相对于自由下落系统可以大大降低料浆对管道的冲击磨损和管道所受的压力，且分级尾砂满管流输送系统的管道出口压力随充填倍线的增大而减小，系统总压力基本保持不变；管径的变化对充填料浆的水力坡度具有很大影响，变径管措施有助于深井充填中实现满管流输送；当充填倍线N=6.0时，该矿山分级尾砂在实现满管流输送的同时，弯管处压力损失达到最小值0.247 MPa。, correspAuthors=null, authorNote=王新民，教授，研究方向为采矿与充填技术，电子信箱：wxm1958@126.com, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null,
