Assessing the current status of underground mine ventilation system in ThanhCong- CaoThang area, HonGai coal company, QuangNinh region, Vietnam

Abstract

In underground mine ventilation, there are many causes affecting the efficiencyof mine ventilation, even affecting mine safety. In order to have an effective mine ventilationsystem, the research and evaluation of mine ventilation, in order to get timely solutions toimprove the efficiency of mine ventilation, is essential and must be done. regularly.Thanh Cong - Cao Thang coal mine area of Hon Gai Coal Company, Quang Ninh region, Vietnamis a mine exploited underground. The nature of this mine is the consolidation (connecting) ofThanh Cong areas and CaoThang areas in the period of 2016. After consolidation into Thanh Cong- Cao Thang mine, many factors in the mine ventilation system of The mine site is altered andaffects the efficiency of mine ventilation. This article has analyzed and evaluated the current statusof Thanh Cong - Cao Thang Area Ventilation System to help research and select appropriatesolutions to promptly improve the efficiency of mine ventilation and ensure security, ensure a safeenvironment and reduce the cost of mine ventilation.
