我矿井下矿仓至选厂相距1500 m,其中地表距离约300 m。在天睛和气候干燥季节,残留在矿车壁上的粉矿岩浆易被太阳晒干,在矿车运动中受到振动后,便变成微细粉尘不断飘扬,造成运输巷道风流严重污染。同时,也污染了卸矿场翻斗工的劳动环境。根据我矿所使用的电机车驾驶室无防水装置以及矿区水源不甚充足的实际情况,不能在入风井口安装长期喷雾水幕,而安装了间歇喷雾的附线式矿车自动水幕。附线与
Mine mine to mine from the election plant 1500 m away from the surface distance of about 300 m. In the days of the earth and in the dry climate, the ore-bearing magma remaining in the wall of the mine car is easily sun-dried. After being shaken in the movement of the mine car, the fine dust is constantly fluttering, resulting in serious pollution of the roadway. At the same time, it also pollutes the work environment of dumppers in dumping sites. According to my mine used electric locomotive cab without waterproofing device and mine water is not sufficient enough actual situation, can not be installed in the air wellhead long-term spray water curtain, and intermittent spray installed intermittent tub automatic water curtain. With the line and
