摘要

This article presents the chemistry of deposited mining wastes in the Debiensko (Upper Silesia, Poland) coal mine as well as the process and dynamics of pollutants released from the wastes located in this landfill. The main stages of migration in the water solution have been emphasized as well as changes of chemistry and the dynamics of their spreading. The article also shows the impact of pollution both in the aeration zone and upon surface and underground water in the area of landfill. It was stated that the level of water degradation caused by depositing of coal wastes is high and it is related to chlorides and sulfates and -in the last phase of rock weathering - with iron.
