MATLA WILL MAXIMISE RESERVES

Matla is an underground operation and the last Exxaro-owned, Eskom-captive mine, situated west of Kriel, Mpumalanga.

We currently run four interrelated Life of Mine (LOM) projects there, with an estimated capital cost of R3.5 billion:
 
  • Matla Mine 1 Relocation (MM1R)
  • Short Wall Replacement (SWR)
  • North West Access (NWA)
  • Mine 3 Vent Shaft (M3VS)

The four LOM projects will help Matla mine to comply with the Eskom Coal Supply Agreement (CSA) until the closure of Matla power station in 2033.

Matla Mine 1 Relocation aims to provide safe access to the remaining coal reserves. The scope includes development of a new box-cut, as well as the construction and commissioning of all needed surface infrastructure. The first phase of detail design has been completed and full implementation is pending funding approval from Eskom.

Matla Mine currently runs both Short Wall (SW) and Continuous Mining (CM) operations. The geological conditions that support SW mining methods are deteriorating fast, therefore, the SWR project has been undertaken to replace the SW equipment with CM equipment, at Mine 1.

The North-West Access project will enable access to the remaining mineable reserves through the development of inter-seam tunnels between Mines 2&3.

The last of the four projects, M3VS, entails the design, construction and commissioning of a new vent shaft, and all its supporting infrastructure. The current ventilation at Mines 2&3 is only sufficient to operate one CM section, but with the addition of more CM sections, more ventilation is required.

Both MM1R and NWA are awaiting approval from Eskom (expected in 1Q2018), while SWR is dependent on approval of MM1R. The M3VS project is currently in BFS (Bankable Feasibility Study) phase, and is expected to be completed by April 2018.
