Abstract: The integration and application of dual-way long-distance pipeline transport of water and iron concentrate,and dry tailings stockpiling is an integrated science technique including fluid mechanics,ecological environment,mine safety etc.and has been successfully applied in Baotou Steel corp.The integration and application of the technique solves the bottleneck problem that industrial water restricts the development of Baotou Steel Mining Area.It modified the traditional railway and highway transportation for ore and the traditional tailings stacking mode of damming at surrounding.Also,it realized the strategic transfer of Baotou Steel raw materials base,and the efficient development and utilization of low grade ore respectively.A new model of green and efficient development and utilization of metallurgical mineral resources in China was established,which created conditions for re-utilization of rare earth resources remained at tailing pond.This technique has reference for tailings stockpiling and pipeline transportation construction and plays a leading role in exploring mineral resources in the high-cold water-deficient region.It also is of significance in improving the people's livelihood and ecological protection,keeping resource and environmental protection and production safety,and enhancing the competitiveness between enterprises.

Key words: Pipeline transport, Dry tailing stockpiling, Integration and application, Iron concentrate
