The article discusses the possibility of improving themicroclimate in underground hard coal mines in Vietnam. Vietnameseunderground mines are shallow mines which extract coal depositsaccumulated up to 500 m below ground. According to the currentVietnamese laws, coal deposits can be mined if air temperature does notexceed 30oC, although this rule is not always observed, especially duringsummer. This article analyses the impact of air parameters on the climaticconditions in headings and the use of the air temperature reduction methodin selected underground mines in Vietnam.
