煤矿大断面风桥施工工艺技术应用

Analysis and application of large section wind bridge construction technology in coal mine

风桥是矿井通风中重要的通风设施,它可有效将新鲜风流与污风分割开,但由于受施工条件限制,复杂条件下对于大断面风桥施工难度较大,在施工过程中不仅施工效率低,而且存在很大的安全隐患,对此同煤集团马道头矿掘进队组在施工2105皮带顺槽风桥时,通过分析研究对大断面风桥施工采取合理有效的施工工艺,力求保证风桥安全顺利施工。

Wind bridge is an important ventilation facilities in mine ventilation,it can effectively will fresh wind flow and pollution are cut in the wind,but due to the construction conditions,complex conditions for large cross section airbridge construction is difficult,not only in the process of construction construction efficiency is low,and there is a big security hidden trouble,this same headquarters of excavating in coal group.Head of mine in the construction of 2105 belt along the groove wind bridge,through the analysis and research of large cross section airbridge construction take reasonable and effective construction technology,makes every effort to ensure the safety of airbridge construction smoothly.
