摘要
在掘进过程中由于钻眼、爆破、转载、运输、喷浆等生产环节以及通风方式致使施工巷道产生大量粉尘,对现场施工人员身体健康造成极大危害,影响了巷道施工现场质量标准化,同时对于煤层高瓦斯易燃矿井很容易引发煤尘爆炸事故。雁崖煤业公司技采取有效措施对掘进巷道粉尘进行治理,取得了显著成效。
A groat deal of dust occurs at construction roadway during tunneling due to the production links of drilling,blasting,transferring, transporting and grouting and ventilation mode,which does great harm to construction workers＂ health ,reduces the quality standardization of roadway construction field and brings coal dust explosion in high-gas coal mines.The paper presents some effective measures of dust control, which can greatly reduce the dust concentration in tunneling roadway.
