GEM Projects specialises in the use of fly ash as a backfill material. Fly ash backfilling has a long history in coal mines, given the usual close proximity of Power Stations.
The use of fly ash in backfill for the following reasons:
- Lowest cost option
- Fly ash is complementary to the cement binding reaction whereas tailings requires more cement to cure
- Fly ash is a waste product from Coal Fired Power Stations, comprised of round spherical <150 micron, amorphous incombustibles
- Dry pneumatic handling = fully sealed handling.
