Mine ventilation aims to dilute toxic gas concentrations, dilute dust concentrations, remove them from the mine and ensure pleasant microclimate conditions in the mine, especially at work sites. Currently, in underground coal mines in general and in Giap Khau mine area, Hon Gai coal company, in particular, is in the process of converting the mining area into deep, as well as increasing output. Therefore, it is important to ensure that ventilation is a top priority in long-term occupational safety and meets the plan to increase coal production. In this study, we have evaluated the current state of ventilation in Giap Khau mine area. From those research results, on the basis of computational research methods, we have come up with reasonable solutions to change and improve ventilation efficiency for the mine in the condition of complicated mining plan and technology characteristics are still limited compared to those in the world. Specific solutions solve 2 problems: First, ensure ventilation for the current mining operation stage; Secondly, we have researched and proposing suitable solutions for ventilation of Giap Khau area mine when it has to increase production and move down to an adjacent project at a deeper level.

Zwiększająca się głębokość pokładów węgla w kopalniach podziemnych ogólnie mówiąc a szczególnie w kopalni Giap Khau i związany z nią wzrost temperatury pierwotnej górotworu są powodem pogarszania się warunków mikro-klimatycznych pracy górników i wystąpienia zagrożenia klimatycznego w przodkach górniczych. Wentylacja ma na celu rozrzedzenie stężeń gazów toksycznych, rozrzedzenie stężeń pyłów, usunięcie ich z kopalni oraz zapewnienie przyjemnych warunków mikroklimatycznych. W artykule, przedstawiono wyniki oceny aktualnego stanu wentylacji w kopalni Giap Khau i odpowiednie rozwiązania, które pozwalają poprawić efektywność systemu wentylacji zwalczając zagrożenie klimatycznych kopalni.
