Zibulo Colliery falls within the Springs-Witbank Coalfield, that comprises of sediments of the coal-bearing Ecca Group of the Karoo Sequence, which were deposited on an undulating pre-Karoo floor which had a significant influence on the nature, distribution and thickness of many of the sedimentary formations, including the coal seams. Locally the general lithological profile, up to, and including the deepest mine-able coal seam, comprises of soft overburden overlying coal seams 5 (shallowest) to 1 (deepest) (Licebo Environmental and Mining (Pty) Ltd, 2018). Below the No 1 coal seam is the basement, comprising a diamictite of glacial origin (Licebo Environmental and Mining (Pty) Ltd, 2018). The entire sequence has been extensively intruded by pre-Karoo dolerites (for the regional area). The Ogies dolerite dyke runs in an east-west orientation across the centre of the Zibulo opencast mining area (Licebo Environmental and Mining (Pty) Ltd, 2018). Two other dolerite dyke intrusions were identified on the eastern edge of the project area running in a north to south direction. Zibulo OC is located in the Witbank Coalf ield where typically five coal seams are present. However, at Zibulo OC only three seams occur, ie from bottom, the No 1 Seam, the No 2 Seam and the No 4 Seam at the top. The No 5 Seam has been eroded and the No 3 Seam is not present. The No 4 and No 2 Seams both contribute to the colliery’s export product. Zibulo OC is sub-divided into two distinct domains, north ........

Zibulo Colliery consists of two parts, namely an underground development located approximately 25 km South West of Ogies and a small opencast section located immediately North West of Ogies.

Zibulo UG is a bord and pillar operation targeting a selective mining horizon between 3.3m and 4.5m thick in the No 2 Seam. The mine was designed to operate with eight sections. During 2021 a prime section was established to improve the production rates.

The operation is equipped with CMs, shuttle cars, feeder-breaker systems and conveyor belt systems. The UG infrastructure consists of a vertical shaft for transporting man and material, an incline shaft for the conveyance of coal and an appropriate ventilation system.

Coal mined at the Zibulo Underground Colliery is transported directly to the plant by means of an interconnecting conveyor system, Zibulo Opencast coal is road hauled.

The Zibulo Colliery opencast operations consist of a single pit operation with a pit length of almost 1 km and is classified as a mini pit. Zibulo Colliery has two active mining cuts, namely the North and East cuts.

The coal is combined with the Zibulo UG coal, producing a saleable 6,000kcal/kg NAR export product and a 4,800kcal/kg NAR middlings export product.

The Zibulo OC operation supplements the underground production ROM to the Phola Coal Processing Plant (PCPP).
