高瓦斯矿井掘进工作面快速除尘系统的应用

摘要

For high dust concentration of high -gas tunneling face,put forward the rapid dust removal system which is mixed ventilation of long-indentation and short-extraction combined with closed wet dust removal device, analyzed the key parameters that affect the ventilation system arrangement,established the closed wet dust removal system.It showed that this system reduced the dust pollution of excavation roadway effectively by contrasting the dust concentration before and after use.%针对高瓦斯掘进工作面粉尘浓度较高的问题，提出了长压短抽式混合通风与密闭湿式除尘装置相结合同步作业的快速除尘系统，分析了影响通风系统布置的关键参数，建立了密闭湿式喷雾除尘系统。通过对比该系统使用前、后的粉尘浓度，表明该系统有效控制了掘进巷道的粉尘污染。
