经验表明,为保证井下采区通风监控系统的正常工作,安设两个沼气传感器即可。一个传感器安设在工作面回风流中,以便当沼气浓度超限时,切断采区电源,另一个传感器安设在采区回风流中,向计算中心传送信息。
Experience has shown that in order to ensure the normal operation of ventilation monitoring system in underground mining area, two biogas sensors can be installed. A sensor is installed in the return air flow in the working face so as to cut off the power supply of the mining area when the biogas concentration exceeds the limit. The other sensor is installed in the return air flow of the mining area to send information to the computing center.
