Spoils Handling From Coal Mines In The Waterberg Coalfield Area, Limpopo
The 11 coal-bearing zones currently being mined at Exarro's Grootegeluk mine, discard intraburden onto discard dumps. During mining operations the open pit will be backfilled with plant discards, overburden and interburden on completion of mining. The plant waste will be covered with overburden and topsoil. Intraburden spoils consist of sandstone, mudstone and shale rich in minerals such as pyrite and siderite.
