Measures of reducing consumption of main fan power

昼夜运行的主要通风机是煤矿耗电最多的设备之一，应采取有效措施降低电耗。结合尚义煤矿实例，对通风阻力不大、需风量不多、主要通风机能力过剩的地方小型矿井，如何选定主要通风机经济运行方案进行了阐述。

Main fan working in coal mine day and night is of the most power consumption equipments. It is of great meaning to take effective measures to reduce its power consumption. By practice in Shangyi Mine, the article expends how to choose the economic operation patterns of main fans in local small-sized mines of weak ventilation resistance, low required airflow with oversupply of airflow from main fan.
