大断面巷道过风氧化带关键技术研究

Research on Key Technologies of large-section roadway driving wind oxidation zone

为了研究掘进工作面过风氧化带的施工工艺,总结出了组合支护技术和大断面巷道过风氧化带的先组合支护施工导硐、后注浆替棚刷扩的技术,并将组合支护技术进行了现场应用,证明该技术过风氧化带的安全性、可行性,为采掘工作面过风氧化带提供了一整套的关键技术,具有很强的指导和推广价值。

In order to study on the construction technology of the driving face passing wind oxidation zone, summed up the combined supporting technology of large-section roadway driving wind oxidation zone that firstly construct the pilot tunnel, and then grouting for shed brush expansion technology, the successful application of the combination supporting technology in the field, prove safety and the feasibility of the technology of oxidation, which provides a set of key technology for working face wind oxidation zone, with strong guidance and promotion value.
