backfilling at low temperatures

[emrah26teng]

I have to excavate and backfill about 15000 m3 borrowpit sand. It has to be done during winter season and specs does not let us work below -5 Celcius. So I have to find out a way to keep the subgrade warm ready to go. Do you have any suggestions.

Is this a road?

A case history at a large western Canada mine. They did borings of tailings dam and the log came out sandy ice!!!

Good question - give us more details and we'll go from there!
