Abstract:

Mine ventilation purposes diluent and taken out of the pit of harmful gases released during the mining process and ensure the conditions suitable microclimate in the work place. Currently, in the underground coal mines in general and in particular Hồng Thái mine is in the process of moving deep exploitation, ensure ventilation requirements should be given special attention and become important tasks in the work ensure safety and response plans to increase coal production. From research results, review current Hồng Thái ventilation network, articles proposed measures to furthering the opening hours, improving the efficiency of the existing station ventilation in the mine.
