大倍线充填料浆管道输送困难及输送浓度偏低等问题是影响矿山充填效益的关键因素，如何低成本实现大倍线高浓度充填料浆的输送，是充填管道输送研究的重要课题。基于宾汉流体（B-H）的Buckingham方程，开展高浓度尾砂浆大倍线自流输送管道优化研究，结合安庆铜矿马头山矿段充填浓度低和输送倍线大的实际情况，采用分段计算、局部优化的方式，以较低的成本实现了安庆铜矿马头山矿段充填管线的优化工作，通过优化改造，输送效果得到明显改善，充填浓度提高了2%，为矿山创造了良好的综合效益。

Miles of pipelines are needed for the slurry transporting form the filling slurry preparation station to the goaf （filling stop） underground.Restricted by the spatial condition of orebody，slurry pipeline is usually connected by several vertical and horizontal sections，once the horizontal distance between the goaf to station is far from each other，the problem which called larger fill-times-line pipe transport（LFTLT） system is made.It is difficult to transport high density filling slurry by a LFTLT，therefore，many mines have to choose a lower density slurry instead therefore causing poor filling quality.So，how to transport high density filling slurry at a low cost is an important subject.Pumping slurry is usually used for LFTLT，such as supplying energy of paste slurry through plunger pump.However，the direct problem of power-transmission is high energy consumption and high cost.For many large-scale metal mines，such as iron ore and copper ore mines，filling materials consume a lot and transportation needs is large.Pumping filling is often high cost，thus restricts its extensive using in the transport process.How to optimize the slurry transport system to make true low cost，high efficiency and safety using is particularly important and also has important practical significance.The flow characteristics of high concentration filling slurry in pipeline can be expressed by Bingham flow pattern mathematically，it’s a linear non-newtonian fluid which means the fluid will flow only when the shear stress exceeds the initial shear stress，and the viscosity coefficient of the fluid is a constant.Because this flow pattern is simple in equation form and convenient in calculation and analysis，a large number of research practices has been done and show that this flow pattern is more in line with the total tailings cemented filling slurry with a concentration of more than 65%.In this flow pattern，scholars have made fruitful achievements in tailing slurry transport，providing beneficial exploration for energy saving and efficiency increasing in this field，also achieved good results.On the basis of predecessors，this study work on optimization of self-flowing pipeline system which be used for tailings slurry concentration beyond 68%，and belongs to the LFTLT system.The main research method is using of the Buckingham equation of Bingham fluid （B-H），combining with the actual situation that low filling density and large fill-times-line in MTS section of Anqing copper mine.Pipeline optimization is also carried out in this paper，after that，the technical reconstruction has been taken，as a result，it is shown that the transportability has been obviously improved，the goal of increasing filling density by 2% has been achieved，which obviously created a comprehensive benefit.
