| Abstract: |
| The author explores the relationship between the filling times line, the vertical elevation difference of slurry inlet outlet point and the outlet velocity in view of the gravity transportation problems of backfilling slurry by pipelines by using technique methods of the theoretical derivation to slurry pipeline tranportation hydraulic characteristics , numerical simulation and actual site observation. Then the formula of outlet velocity of slurry and the vertical elevation differences is deduced under the condition of the same filling times line, which has been verified in the process. In the last part, the author has made the conclusion: Slurry outlet velocity rises with the increasing of the vertical elevation difference under the same filling times line, and it is reduced with the increasing of filling times line under the same vertical elevation difference . |
