Description:   Techniques for mine tailings disposal were discussed. Traditional mine backfill disposal is only sufficient for about 50% of the volume of the rock originally taken out due to crushing increased volume, and most mines only return 20-35% of tailings underground.  Problems inherent in such procedures and the advantages offered by paste fill were discussed.  Paste fill allows the incorporation of extremely fine particles which normally compromise structural stability and hydraulic conductivity, and the paste is also a more effective support medium.  The liquefaction caused by seismic vibrations and consequent spills of muddy tailings from previously dried tailings was also discussed.
