进入80年代后,由于新型矿用节能风机的推广应用,以及通风系统考核指标的实行,很多地下矿山发现原来设计的主扇统一通风系统存在很多问题,如通风能耗高、漏风大、有效风量率低等,不能满足生产需要。为此,马鞍山矿山研究院提出了多级机站可控式通风系统新技术。经过七、八年的研究和应用实践证明,该系统具有控风能力强、有效风量率高、能耗低以及便于风量调节等很多优点,得到了广泛的应用。
Since the 1980s, due to the popularization and application of new mining energy-saving fans and the implementation of ventilation system assessment indexes, many underground mines have found many problems in the original design of the main fan uniform ventilation system, such as high ventilation energy consumption, large air leakage and effective air volume Low rate, can not meet the production needs. To this end, Ma On Shan Institute of Mine proposed a multi-station controllable ventilation system, new technology. After seven or eight years of research and application practice, it has been proved that the system has many advantages such as strong wind control, high effective air flow rate, low energy consumption and convenient air flow regulation. It has been widely used.
