摘要
本文通过对司马矿的综掘面粉尘进行现场实测,得出了该矿综掘面全尘及呼吸性粉尘的运移规律。研究显示,掘进工作面处粉尘浓度最大,向后依次减小,其中呼吸性粉尘占全尘的78%左右。建议采用喷雾、泡沫除尘、抑尘剂抑尘等各项措施。
This article through to syma ore comprehensive tunneling field measurement of dust,it is concluded that the mine comprehensive tunneling face full of dust and dust migration rule.Research shows that maximum,dust concentration tunneling faces backwards,in turn,reduce the dust accounted for about78%of the total dust.Recommended spray,foam dust,dust suppression agent dust suppression measures.
