Abstract:

The mechanised longwall face 11-1.15 at Halam coal mine is one of the most productive mines owned by Vietnam National Coal - Mineral Industries Holding Corporation Limited (VINACOMIN). In order to ensure an efficient working environment in the face, the management of air environment including temperature and ventilation is of extreme necessity. This paper first analysed the current operation and ventilation of Face 11-1.15 and then proposed an advanced solution for managing the air environment. By using the proposed solution, it is observed in the face that the temperature and wind ventilation indices are now satisfactory according to the national standard norm QCVN 01/2011-BCT regarding working conditions.
