Mine Life3 years (as of Jan 1, 2020)
The Khanyisa Complex comprises the historical Khanyisa mining area (mined-out), the Catwalk and the Triangle areas, all of which have been consolidated into one mining complex.

CompanyInterestOwnership
Wescoal Holdings Ltd. 100 % Indirect
The Khanyisa mining complex was consolidated into one mining right. An amended mining right was granted in May 2017 and is underpinned by a joint venture in respect of the Triangle area. Wescoal now owns 100% of the Triangle area after acquiring the 65% that was previously owned by UJU Resource Proprietary Limited.

Deposit Type

  • Sedimentary


Summary:

Khanyisa Colliery falls within the Witbank Coalfield. There are five major coal seams – named 1 Seam through to 5 Seam from the base upwards - which are generally contained in an approximately 70 m thick succession of Karoo sediments (Vryheid Formation) consisting predominantly of sandstone with subordinate mudstone, siltstone and shale.

Although the parting thicknesses between coal seams are regionally constant, they become variable towards the northern margin of the coalfield. Strata overlying the 5 Seam are mainly arenaceous.

The period of Dwyka glaciations resulted in a highly irregular and undulating floor onto which the Karoo sediments were subsequently deposited. The result is that the coal seams are discontinuous over prominent palaeographic highs. Not all the seams are always present and the distribution, nature and thickness of the seams are strongly influenced by the palaeotopography of the original surface of accumulation, as well as by post-Karoo erosion.

The Khanyisa Colliery asset hosts the Witbank Coalfield coal seams, of which 4 and 2 Seam within the Vryheid Formation (Ecca Group) are exploited at Khanyisa and the 4 Seam is exploited at Sarie Marais in opencast operations. Post-Karoo dolerite sills have greatly affected the distribution and quality of the coal measures in the Khanyisa Colliery area.


Mining Methods

  • Pillar & roof
  • Truck & Shovel / Loader


Summary:

Fixed infrastructure is utilised with all major mining activities contracted out, together with the crushing and screening plants. Additional mining contractor infrastructure was established to provide for the full service.

Both Triangle and Catwalk areas are mined opencast, with the difference being that Catwalk extracts mainly the No. 2 seam pillars and roof coal left by previous underground mining.

Current mining in Triangle is taking place on the remainder of Triangle South as well as Triangle North (No. 4 and No. 2 seams).

Work has commenced on the Triangle North Block with the extraction of some unplanned No. 5 seam. No. 5 seam was not planned as it was not evident in the recently drilled boreholes.
