Abstract:

Mine ventilation plays a significant role in underground mining, especially in mining at depths greater. Ha Lam Coal Mine is one of the mines in greater depth and tend to continue to further exploit, so ventilation issues need to be deeply concerned.The paper has analyzed and evaluated the status of the mining ventilation system of HaLam coal mine. Therefore, authors provide the most appropriate solution on renovation of ventilation system in order to improve and reduce the cost for mining ventilation
