- In the most recent years, the Vietnam National Coal - Mineral Industries Holding Corporation Limited (VINACOMIN) has been dynamically developing mechanization technologies in underground coal mines. The climatic conditions of Vietnam, as well as increasing the depth of the coal seams and the production capacity, contribute to an air temperature increasing in mining excavations. The article presents statistical equations enabling air temperature forecasting at the outlet of mechanized longwall workings. The results of numerical calculations, obtained from the solutions of the adopted mathematical descriptions, were compared with the measurement results and the statistical significance of the obtained deviations was determined. The performed analysis allowed to assess the practical usefulness of the adopted model for the air temperature forecasting in the workings of mechanized underground mines in Vietnam. The presented method can be used as a tool for mining services in the fight against the climate threat in underground excavations.
