本文通过对工字钢棚交叉支护技术在3下106采面切眼支护中的应用技术实践,提出了在以后大跨度切眼施工支护中特别是顶板破碎、地质结构复杂、大跨度切眼均可采用此种支护支护施工方案的建议。
In this paper, through the practice of cross-support technology of I-beam steel shed in 3 under 106 face cutting eye support, put forward that after long-span undercut construction support especially in the roof crushing, complicated geological structure, large-span Cut eye can use this kind of support construction proposal.
