Study on Hydrodynamics Model of Total Tailings Filling Slurry Dehydration

Table 1

Summary of research achievements in dewatering technology of whole tailings.

Type	Method	Pros and cons
External effect	Electro-osmosis [11–14]	The above dehydration method has good dehydration effect, but the cost is high, the related supporting technology is complex, and there are potential safety hazards
	Negative pressure method [15]
	Forced air method [16]
	Chain dewatering method [17]
No external effect	Setting dewatering closed wall and dewatering well [18]	This can improve the dehydration speed to a certain extent, but also lead to the increase of dehydration cost
	Increasing the spacing and diameter of dewatering pipe [19–21]
	Adding a certain amount of coarse particles to improve the particle size distribution [22]
