轻放工作面切眼施工技术的应用

On application of open-off cut construction technique

结合掘进大断面切眼施工技术的实践,总结出轻放工作面切眼施工技术要点,通过采用导硐和刷帮掘进技术和锚网索支护技术,能够保证施工安全、工程质量及支护强度等,应用此技术可很好地解决大断面巷道掘进难题,同时也节约成本、确保安全、提高经济效益。

Combining with the practice of tunneling large section open-off construction technique,the paper sums up the technical points for the open-off cut construction,through adopts the pilot drifting and brushing tunneling technique and the bolt-mesh-anchor support technique to ensure the construction safety,the engineering quality and the support strength,and indicates the technique can solve the tunneling difficulties of the large section,save costs,ensure the safety and promote the economical benefits.
