Abstract:

For the purpose of improving the reliability of backfill pipe transportation system，based on engineering fluid mechanics，computational fluid dynamics and pipeline self-flowing transportation theories，low pressure full-flowing transportation mechanics was put forward，which aimed at dealing with the tremendous impact wear and instability of pipeline transportation in a mine，combined with numerical simulating and analyzing by the software of FLUENT.The results show that the low pressure full-flowing transportation system can largely alleviate the max pressure in pipeline system，compared with high pressure full-flowing transportation system.When the value of k is 0.53 and increasing flux to 80 m3/h simultaneously，the full-flow ratio of this system is able to be improved by about 8 times.The piping failure can be reduced remarkably and make sure the stability of the slurry flowing by implementing the plan three.

Key words: paste backfill, self-flowing transportation, pipe wear, full-flow, numerical simulation
