Abstract
Because of the high degree of automation in the coal mining industry in the Ruhr area, Germany, about 1 metric ton of crushed rock/colliery spoil is brought to the surface for every metric ton of coal. Most of the colliery spoil disposed of must be dumped. These colliery spoil dumps are anthropogenic geological sediment bodies, which have a characteristic “facies” resulting from geological, technical, and economical factors connected with the formation of the dumps. The relation between the facies of the dumps and these factors, for example, is examplified with the pyrite content within the colliery spoil. Pyrite content within the dumps is dependent both on the conditions during sedimentation and (early) diagenesis and the techniques used for mining and processing. Thus, this “geologic-technical” facies of the dumps controls the weathering processes on and in dumps. These humaninduced processes are mainly responsible for the environmental impact on soil and groundwater. Oxidation of pyrite as well as alteration of pyrite under anoxic conditions yields dissolution of carbonates, accompanied by gypsum formation, by acid attack and strong acidification takes place.
