UCML produces thermal Coal which is highly volatile with strong combustion characteristics. This coal is sold domestically and internationally for use in power generation and general Industry use.

The Coal produced at UCML is categorized as:

  • Domestic Grade (22.5% - 25% Ash)
  • Premium Coal (12.5% - 14.5%)

The domestic coal is predominantly sold to local power stations, however some is exported overseas. All the Ulan Premium Coal is exported overseas.

Merit of Ulan Coal

Ulan coal is of uniformly high quality, with

  • excellent handling properties
  • excellent combustion characteristics
  • low carbon-in-ash
  • low sulphur
  • low nitrogen
  • low phosphorus
  • low slagging index
  • low fouling index
  • high ash fusion temperatures
  • ability to maintain full design superheat and reheat steam temperatures at lower loads

Ulan's mining expertise and modern technology enable the production of consistent quality coal from a single thick seam.
