摘要/Abstract

摘要： 通过对下峪口煤矿1110回风巷道原U型棚支护的失稳机理、采动影响、围岩物理化学性质和底板破坏特征的分析，得出围岩失稳破坏的主要原因，并根据结构补偿原理提出了高应力破碎煤层巷道棚-索协同支护技术。通过对围岩变形信息的检测，表明该支护技术有效的控制了巷道围岩变形。

Abstract: Through the analysis of the instability mechanism, mining effect, physicochemical property of surrounding rock and floor failure characteristics of original U shape shed support of 1110 air-return way in the Xiayukou Coal Mine, the main reason which caused the unstable failure of surrounding rock is obtained. According to structure compensation principle, high stress broken seam tunnel shed-cable collaborative support technology is proposed. Through the test of deformation information of surrounding rock mass, it proves that this support technology effectively controls the surrounding rock mass deformation of tunnel.

Key words: Adjacent Mining face, Influence of mining, Structure compensation, Shed-cable collaborative support
