微喷雾及自动隔爆装置在矿井中的应用

Application of small spray and automatic flameproof device in mine

传统煤巷掘进工作面净化水幕为钢管连接喷雾头、隔爆水棚采用横担与纵担钢管吊挂的方式,存在净化水幕喷头经常堵塞、隔爆水棚不能满足单轨吊运行的需要等缺点。通过微喷雾代替传统净化水幕、自动隔爆装置代替传统隔爆水棚,有效的满足了工作面防尘需要及单轨吊正常通行,减少了作业环节,提高了防尘效果,净化了工作环境。

The traditional water purifying curtain for the coal roadway heading faces is connected with the spray head of the pipe connection and the flameproof water shed by means of the hanging of the cross arm and the longitudinal bearing steel pipe,There are many defects such as the frequent clogging of the water curtain sprinkler and the need for the flameproof water shed to meet the needs of the monorail operation.Instead of the traditional flameproof device,the small spray instead of the traditional flameproof water shed effectively meets the needs of dust prevention in the working face and the normal traffic of the monorail,reduces the operation links,improves the dustproof effect,and purifies the working environment.
