为满足桦树沟铜矿充填物料的供应、实现高海拔地区沉降性颗粒物料浆体长距离管道连续输送的目的,进行了尾矿输送工程研究与工业应用试验,结果表明,浓度为40％ ～ 45％的尾砂浆在上扬高度超过200m的输送过程中,管道输送压力基本保持在4.1 ～4.6 MPa,物料供应充足及浓度稳定时,管道进、出料口及各关键部位均可保持正常工况.正常充填生产时,尾砂浆源源不断地输送至高处山体之中的地下充填站,输送流量与输送浓度满足了日常生产的需要.%In order to meet the needs of the Huashugou Copper Mine filling material supply,to achieve high altitude settlement to particles in long distance slurry pipeline continuous conveyor,the engineering design research and industrial application test fortailing transportation were carried out.The results show that the concentration of 40％ ～ 45％ mortar conveying process in the tail up height of more than 200m in the pipeline pressure keep in 4.1 ～4.6 MPa.When the material supply and stable concentration,inlet and outlet pipes and all key parts can maintain normal working conditions,and when the normal production of tailings slurry filling,the material supply can be transported to the high mountain in the underground filling station and transportation flow and transportation concentration can meet the needs of daily production.
