PROVJETRAVANJE U RUDNICIMA REPUBLIKE ČEŠKE I UKRAJINE

The present-day micro-climatic conditions in black coal mines are of such nature that in no mine natural micro-climate conditioning is sufficient any more. The original temperature of rocks grows progressively in dependence on the increasing depth of the extracted seam, or more precisely, on the mining workplace, and this growth is much more significant than previously considered. The temperature of the surrounding rocks, but also high-performance continuous miners and conveyor belt drives heat up airflow, thus worsening microclimatic conditions. This article describes micro-climatic conditions the in Czech Republic and Ukraine and some methods of deep mines air conditioning.Današnji mikroklimatski uvjeti u rudnicima bituminoznog ugljena su takvi da prirodni mikroklimatski uvjeti ni u jednom rudniku više nisu zadovoljavajući. Leţišna temperatura stijena raste progresivno s povećanjem dubine eksploatacijskog sloja ili preciznije mjesta dobivanja i taj rast je značajniji od prethodno razmatranog. Temperatura okolnih, pratećih stijena, ali takoĎer i visokoučinkoviti strojevi za kontinuirano dobivanje i pogon transpotnih traka zagrijavaju zračnu struju i tako dodatno pogoršavaju mikroklimatske uvjete. Rad opisuje mikroklimatske uvjete u podzemnim ugljenokopima Republike Češke i Ukrajine i neke metode provjetravanja dubokih rudnika
