An analysis of self-ignition of mine waste dumps in terms of environmental protection in industrial areas in Poland
Abstract The aim of the paper was to work out a new comprehensive methodology to monitor thermal activity at mine waste dumps. The methodology was tested through monitoring thermal phenomena occurring in the areas of extractive waste dumping facilities located in the Upper Silesian Coal Basin, Polan...
