This picture shows the adit leading into Zululand Anthracite Colliery (ZAC), near the town of Ulundi, in KwaZulu-Natal, which operates an underground, deep-level, narrow-seam operation using both continuous miners and drill-and-blast mining techniques. ZAC currently extracts about 65 000 t of run-of-mine coal from its three shafts, which it supplements with about 15 000 t of material from the mine’s discard dump, which is processed through a dense-medium separation plant. The mine currently has a remaining life up to 2027, but there are undeveloped known resources with the potential to be developed in future.
