随着煤矿开采深度的不断加大 ,综合机械化程度的提高 ,矿井通风量也在不断加大。致使局部地区风压过大 ,单靠人力启闭风门存在一定的困难 ,且对风门的维护不利 ,对矿井通风系统的稳定存在一定的威胁。为此 ,结合现场实际 ,研制应用了矿用红外线自动风门启、闭装置 ,应用一年多 With the continuous deepening of mining depth, the degree of comprehensive mechanization, mine ventilation is also increasing. As a result, the wind pressure in local area is too large, there is some difficulty in opening and closing the damper by human power alone, and it is unfavorable to the maintenance of the damper, which poses a certain threat to the stability of mine ventilation system. To this end, combined with the actual site, the development and application of mining infrared automatic door opening and closing device, the application more than a year
