quality control

Quality Control throughout the entire operation is the key to producing and delivering high quality resource to Ulan Coal Mines Limited ( UCML) customers. Coal quality is carefully monitored and controlled during all phases of production and preparation through:

  • Extensive coal quality exploration program built into geological model;
  • Additional strip samples in Open Cut and Underground if required;
  • On Site Coal quality Laboratory;
  • Ability to effectively separate product types on Product Stockpiles;
  • Options to blend at the port if required;
  • Independent coal quality analysis at point of load; and
  • Extensive coal technology and marketing technical support.

These systems ensure that contract specifications are met and uniform quality is maintained. The quality of the insitu coal has been determined by detailed core sampling and analysis. Coal from the Underground Operation is monitored by an on-line ash sampler analyzer as it travels along the coal clearance conveyor system to the surface.

The quality of the saleable product is monitored by an automatic sampler which is located on the conveyor to the product stockpile. The coal in each train is sampled and analysed during discharge at the Port of Newcastle. During ship loading operations the coal is sampled and analysed by an independent and certified superintending company.

Stringent coal quality controls ensure that no extraneous matter contaminates the customer’s cargos and that the coal delivered meets specified quality requirements.
