Involves the use of backfill to suppress and/or control oxidation in underground coal mines.
GEM Projects methodology include proven SWMS, risk assessments and delivery of all site services. Oxidation control options include:
- Dry fly ash suppression of goaf oxidation via surface borehole/s
- Wet fly ash smothering of known oxidation zone in the goaf via surface borehole/s
- Dry fly ash construction of a roadway seal remotely from surface via borehole/s.
