摘要: 为解决传统常规锚杆支护对煤矿深部巷道支护效果不佳的问题,在研究郑庄煤矿7#煤层工作面地质情况的基
础上,基于FLAC3D 软件验证了中空注浆锚索支护技术对深部巷道支护的可行性和优越性,并通过实践工程验证了中空
注浆锚索支护对巷道顶板、两帮位移和围岩应力控制的效果。

Abstract: In order to solve the problem of poor supporting effect of traditional conventional bolt support for deep roadway in the
coal mine, based on the study of geological conditions of 7# coal seam working face of Zhengzhuang Coal Mine and FLAC3D
software, this paper verified the feasibility and superiority of hollow grouting anchor cable support technology for deep roadway
support, and verified the control effect of hollow grouting anchor cable support on roadway roof, two sides displacement and
surrounding rock stress through practical engineering.

 Key words: hollow grouting anchor cable; common bolt support; deep roadway; surrounding rock stress; roadway displacement
