摘　　要：本文通过对影响东乡铜矿水力坡度计算的充填材料物理性质进行测试,并对当前该矿井下管道布置情况展开调研,以确定其最大充填倍线,依据固体颗粒的沉降速度来计算其临界流速,选择金川经验公式对该矿进行水力坡度计算,研究表明该矿膏体充填在当前管道布置下能够实现自流。Through test the physical filling material which can influence hydraulic slope calculation of Dongxiang Copper Mine, and research on the current situation of underground piping layout to determine maximum filling - line. According to solid particle sedimentation rate to calculate critical flow speed. Use Jinchuan＇s experience to caculate hydraulic slope of Dongxiang copper mine, research result improve that mining paste can gravity flowing under the current piping layout.
