Method for the preparation of a wet load of coal with a bulk density of at least 700 kg/m3 by preparing briquettes containing less than 10% wt water from an aqueous slurry of coal fines, such as from a pipeline, and mixing the briquettes with wet coal fines or extrudates or agglomerates thereof containing up to 30% wt water. The briquettes can be prepared by dewatering the slurry, extrudating the obtained paste and briquetting the extrudates; or by agglomerating the coal fines, for example with naphtha, and briquetting the agglomerates, for example by removal of naphtha.
