我矿井下胶带运输机运行时,时常出现无煤或煤少现象,但安装在胶带运输机头的喷雾装置仍照常送水喷雾,结果造成出水煤或胶带打滑,溜煤小井下口装车点的煤水流入大巷。因此胶带运输机司机不得不时常关闭防尘喷水装置,从而又导致煤尘飞扬,大量的煤尘都随着风流方向飘浮,积存在运输机周围50m 左右的地段。煤尘大量积存,不仅污染矿井空气而且还直接威胁矿井的安全生产。为彻底根治这一问题,我矿于1984年
When I run the mine belt conveyor, coal or coal often appear less phenomenon, but installed in the tape transport nose spray device still water spray as usual, resulting in a slip of coal or adhesive water outlet, Flow into the alley. Therefore, the belt conveyor driver had to turn off the dust-proof and water-jetting device from time to time, which in turn led to the flying of coal dust. A large amount of coal dust floated in the direction of the wind flow and accumulated in the area of about 50m around the transporter. Large accumulation of coal dust, not only contaminated mine air but also directly threaten the safety of mine production. In order to completely cure this problem, I mine in 1984
