CASE STUDIES
Proven outcomes.
Lasting benefits.
MINE CLOSURE
Coal
Coal fines are high in clay and resist efforts to dewater. When applied to closing a coal fines dam AMC operations can deliver:
-
A trafficable surface within 16 weeks plus a maturation period (that varys from site to site and usually several months). Once complete the capping process can commence; and
-
A final coal fines density approaching the liquid limit and strengths >10 kPa.
MINE CLOSURE
Mineral Sands
Mineral sand tailings are high in clay and resist efforts to dewater. The low angle of repose is also a contributing and complicating factor. When applied to closing fine mineral sand tailings dam AMC operations can deliver:
-
A trafficable surface within 16 weeks plus a maturation period (that varys from site to site and usually several months). Once complete the capping process can commence; and
-
A final fine mineral sand tailings strength at depth >10 kPa after the maturation period.
