摘要
云岗矿复采81003工作面在初次降尘除尘后,粉尘浓度仍达不到规定的标准。针对此情况设计研制了一款水幕除尘装置,将其安装在距工作面5m处的回风巷道内。数据检测表明:经过二次降尘除尘后效果达到了92%以上,有效地保障了该回风巷道设备和人员的安全。该款水幕除尘装置安装简单,操作方便,适合大面积推广使用。
The dust concentration of 81003 working face after primary dust removal in Yungang Coal Mine is still not up to the prescribed standard. In view of this situation, a water curtain dust removal device was designed and developed, which was installed in the air return tunnel 5m away from the working face. Data test shows that the effect of dust removal after secondary dedusting reaches more than 92%, effectively ensuring the safety of equipment and personnel in the air return tunnel. The water curtain dust removal device is simple to install, easy to operate and suitable for large-scale promotion.
