金川公司二矿区作为有色金属行业中规模最大的下向胶结充填采矿法坑采矿山。因采掘深度约800余m,使得井下通风系统网络庞大复杂。为了有效调控通风系统,在主要巷道中采用风门调控通风系统技术,井下共计安装了约80多道手动风门。为了使风门开启时不破坏通风系统,同时设置二道风门,之间间隔一定的距离。人员或车辆通过时,应开启一道风门,关闭另一道风门。每道风门由二扇门组成,每扇
Jinchuan two mining companies as the non-ferrous metal industry under the direction of the cemented backfill Mining Pit pit. Due to the mining depth of about 800 m, making the ventilation system underground huge and complex network. In order to effectively regulate the ventilation system, the use of damper control ventilation system in the main roadway, downhole total installed about 80 multi-channel manual throttle. In order to open the door without damaging the ventilation system, while setting two air doors, the distance between a certain distance. When a person or vehicle passes, a damper should be opened to close another damper. Each damper consists of two doors, each fan
