自动旋转水幕在巷道通风防尘中的应用
|
摘要
司马矿针对1208巷掘进期间工作面粉尘浓度大、采用传统喷雾洒水降尘效果差等难题,通风队通过技术研究,提出并设计了一套自动旋转防尘水幕并在巷道掘进中进行应用。实际应用发现,自动旋转防尘水幕的应用可使巷道粉尘质量浓度降低至45 mg/m~3以下,提高了巷道质量标准化,取得了显著成效。
Aims at the problem of high dust concentration in working face during heading 1208, poor effect of traditional spray sprinkler and dust reduction, etc. The ventilation team has passed the technical research. A set of automatic rotary dustproof water curtain is proposed and designed and applied in tunnel excavation. The practical application shows that the dust concentration of roadway can be reduced to less than 45 mg/m3 with the application of automatic rotary dustproof water curtain, and the standardization of roadway quality has been improved, and remarkable results have been achieved.
