锡矿山矿务局、湖南冶金研究所、湖南冶金防护防治研究所三个单位共同协作,在锡矿山南矿试验成功矿井通风集中监控、风量自动调节。它利用频分制的单频率讯号已能对一台主扇、20台局扇、10套采场自动风门、30套普通风门以及2套分支风量调节装置进行遥控、遥讯,利用常规测风仪表配合DDZ电动单元组合仪表,能对矿井风量、风压及电机轴承温度进行
Xining Mining Bureau, Hunan Institute of Metallurgy, Hunan Institute of Metallurgical Protection and Prevention of the three units work together to test the success of mine in Tin Mine South Mine centralized monitoring, automatic adjustment of air flow. It uses frequency division of the single-frequency signal has been able to a main fan, 20 Bureau fan, 10 sets of stope automatic damper, 30 sets of ordinary throttle and 2 sets of branch air volume control device for remote control, remote sensing, the use of conventional wind measurement Instrument with DDZ electric unit combination meter, mine air volume, wind pressure and motor bearing temperature
