Study on Pipeline Transportation Experiment of Paste Filling Material

Abstract

The change law of basic paste material performance in the pipeline must be studied to verify long distance transportation in coal mine after the ratio of paste material is completed. This paper introduced simulation system which was developed by us and the pipeline transportation experiment was done. The change law of paste material parameters was studied including collapsed slump, segregation degree and density with pipeline experiment. And the contents of this paper could provide theoretical guidance for field paste filling.
