通过对山西某矿的掘进巷道进行现场实测,得出了该巷道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80%左右。建议采用喷雾、泡沫除尘、抑尘剂抑尘等各项措施。 Through the on-site measurement of roadway excavation in a mine in Shanxi Province, the law of the movement of dust and respiratory dust in the roadway was obtained. The research shows that the dust concentration at the heading face is the largest and decreases in the backward direction. Respiratory dust accounted for about 80% of the whole dust. Proposed to use spray, foam dust, dust suppressants and other dust suppression measures.
