Energy - Poland [71]
Most water used in coal mining can't be reused or put back in the system and then there's evaporation of water
ok I admit - I have very limited knowledge of how Polish coal mines look like - maybe the ground water they have to get rid of (I suppose you agree there is ground water in Polish mines) is not enough or too poor quality to use directly in mining processes (if it is too poor quality the limitation would be the efficiency of cleansing facilities) - so yeah I don't really know if mines use up water from elsewhere (but I somehow doubt it)
I know though there are ground waters in the mines here in Poland and they need to get rid of it : I just read the first sentences of a document about minining in Silesia and it states this: (google translate is your friend)
" Wraz z wydobyciem złóż węgla kamiennego z kopalń w Górno-śląskim Zagłębiu Węglowym (GZW) nieodzowne jest wytłoczenie na powierzchnię
znacznych ilości wód podziemnych, których obecność wynika z poziomej i pionowej strefowości hydrogeochemicznej w obszarze
tego basenu węglowego"
the bolding is mine of course
