Abstract:
Cao Thang coal mine of Hon Gai Coal Company is currently in the implementation phase of the underground mining project at level -50÷ -160 m. It is expected that by and after 2021, the mining coal output reaches double in 2019 (about 300,000 tons/year). On the basis of the assessing results of the current ventilation status in the mining area by auditing the wind network, when increasing the mining output according to the design, this study has calculated the current ventilation demand as a basis for analyzing, evaluating the efficiency of ventilation for the mine site at level -50÷-160 m and considering the future mining project below level -160 m. From there, with the available conditions such as works and equipment of the mine, the authors research and propose the most suitable solutions to complete the mine ventilation system of Cao Thang area mine. Therefore, this is a research work that not only has practical economic and technical significance but also has a long-term orientation for the development plan of Cao Thang coal mine, Hon Gai Coal Company - Vinacomin.
