Investigation of Coal Fines at Coal and Allied Hunter Valley Mine
Coal fines are recognised to have a major impact on the cost and efficiency of the recovery of saleable coal. Fines affect the productivity of the whole mining cycle because of the low yields obtained in washing this material as well as affecting the moisture content and handling characteristics of the final product.
In 1990, Coal and Allied Hunter Valley Mine initiated an internal study into coal fines based on the assumption that a reduction in fine coal in ROM material will lead to increase yields in the preparation plant. The initial results of this study indicated that the level of fines in the ROM coal can be reduced by more than 40 per cent by simple changes in blast design and implementation.
