The information is used to determine in-pit coal mining horizons to meet product coal specification before the mining process commences. During crushing and processing the coal is sampled by fully automated, mechanical samplers. The samples are sent to the nearby external laboratory in Blackwater for analysis.

Product coal is directed towards designated stockpile areas from which haulage blends are proportioned to ensure composite daily quality meets the specifications of the short term shipping schedule.

Stockpiling processes at Boonal Train Loading Facility provide additional homogenisation of the hauled coal. All Jellinbah trains are sampled by another fully automated cross-belt sampler.

Designated stockpile areas at the RG Tanna Coal Terminal at Gladstone ensure minimal risk of contamination from other coal types at the port. All Jellinbah ships are sampled by a fully automated mechanical sampler. Please click here to view a detailed flowsheet of the sampler at RG Tanna Coal Terminal.

All samplers were constructed to the appropriate standard and undergo regular maintenance, inspection and audit for precision and bias.
