Research and Application of Controlled Circulating Ventilation in Deep Mining

With the increase of mine depth, the ventilation is facing great challenges. This paper firstly elaborates the research and status quo of controlled circulating ventilation at home and aboard, and then analyzes its operational principles and introduces application development of the technology in Hongtoushan copper mine. The paper argues that this technology can effectively tackle the problem of ventilation in deep mining and improve the working condition of deep mining by saving energy and reducing consumption.
