为了提高主扇有效风量,加强坑内通风强度,改善作业环境,确保职工身体健康,我矿西山采矿场组成了三结合小组,试制自动风门,以解决由主井短路风流问题。我们参考兄弟矿山的经验,于一九七四年三月试制,同年十月安装成功。经一年多的实践证明,该风门基本满足多台机车在单轨运输巷道运行的要求,机械传动和电气控制部分安全装置比较完善,保证了风门动作安全可靠。允许多台机车通过风门区时,在规定范围内任意距离追尾行驶。同时该风门采用光杆导向装置,使门扇在(80毫米水柱)负压条件下,保持门扇垂直轨道面,保证风门密闭性能。我矿自动风门安装使用后,根据通风效果测定证明,因主井造成的短路风量由18米~3/秒减少到1.5米~3/秒,采矿场所风速提高了0.5～1倍,提高了主扇有效风
In order to improve the effective air volume of the main fan, enhance the ventilation intensity in the pit, improve the working environment and ensure the health of the staff and workers, the mine Xishan Mining Field formed a three-in-a-small group to test the automatic air damper to solve the problem of wind flow shorted by the main shaft. We made reference to the experience of brothers and mines, trial production in March 1974 and installation in October of the same year. After more than a year of practice, the damper basically meets the requirements of multiple locomotives operating in a monorail transport lane. The safety devices of the mechanical transmission and the electric control part are relatively perfect, which ensures the safe and reliable operation of the damper. Allow multiple locomotives through the throttle zone, at any distance within the specified range rear-end driving. At the same time, the damper uses a light rod guide device to keep the door leaf in the vertical track surface of the door leaf under the negative pressure of (80 mm water column) to ensure the air-tightness of the door. After the installation and use of mine automatic damper, according to the ventilation effect, it is proved that the short-circuit air volume caused by the main shaft is reduced from 18m ~ 3 / s to 1.5m ~ 3 / s and the wind speed in the mining place is improved by 0.5 ~ 1 times Fan effective wind
