Salinity Water

The effect of the high salinity water on the compressive strength of mine backfill was studied. Two types of salinity water: saturated and unsaturated brines were employed to mix with mine backfill materials, and the results were compared. The one with saturated brine had high salt content of 400 g/l while the other had 200 g/l. The results showed that compressive strength decreased with increasing salt content. The mine backfill with high salt content (saturated brine) exhibited the poorest compressive strength in which its strength decreased to approximately 50-70 % of the original strength gained from the backfill samples based on water without salt. Additionally, the optimal saline water solid ratio was 0.2.
