This paper describes coking properties of various metallurgical coals and blending techniques based on these coking properties, in relation to the specifications of coke quality required for efficient BF operations. This paper also describes briefly new technology for expanding the scope of .
The proposed blends satisfy basic chemical and mechanical strength requirements at the lowest cost per ton of coal. The blending calculations showed that only low ash, low sulphur, medium volatile and high vitrinite reflectance prime grade coals such as the UK Ogmore should be imported for blending with the ashladen medium coking Lafia coal.
Solid Energy New Zealand operates the Stockton Opencast Coal Mine, a unique deposit consisting of high quality hard coking and thermal coals. Stockton's uniqueness includes high variability of the shipment specifications, strict quality constraints, minimal stockpiling capacity in the coal transport chain and the variability of coal quality both vertically within the seam and laterally...

The effect of substituting fractions of imported coking coals with coke oven tar Bituminous B (RoVr% = –), and coal C falls border line between Bituminous B and C (RoVr% = ), just below and marginal to the prime coking category.
minimise dilution and allows for blending from a range of stockpiles. A tracking database monitors ore tonnes and grades on stockpiles to enable optimal blending for the required plant process performance. The grade control process is described below: DRILLING: Drill burden and spacing are based on the rock types present at Skorpion, 4
Railroad company looks at Port of Grays Harbor in Washington State for coal exports. RailAmerica owns the Puget Sound and Pacific Railroad that serves Grays Harbor. The port's potential coal export terminal, located on a former log yard, could bring another 75 ship calls a year to Grays Harbor.
Should the Coal Committee not promptly select a new Coal Blend following such notification by Seller, then the Coal Committee shall appoint, as soon as reasonably possible, a qualified independent laboratory to sample and test the Coals constituting the Coal Blend to determine whether the Coal Blend will conform to the Coal Blend Standards The cost of such independent laboratory and testing .
sometimes being important. For instance, blending before the Coal Handling and Preparation Plant (CHPP, wash plant) is sometimes needed to improve washability and increase CHPP production rates. The act of blending typically occurs through stockpile stacking however it may also take place within a vessel's hatch during ship loading.
