摘要： 为解决成庄矿五盘区北翼大巷矿压显现强烈， 补强效果差等问题， 提出采用高强锚杆锚索配合滞后注浆支护
技术， 并进行了现场试验。试验结果表明， 采用该设计后巷道迎头80 m 范围顶底板移近量峰值为502 mm， 两帮移近量
峰值为397 mm， 巷道变形量得到有效控制， 有效保证了巷道的稳定性。

Abstract: In order to solve the problems of strong mining pressure and poor reinforcement effect in the north wing roadway of the
5th panel of Chengzhuang Coal Mine, this paper proposed the use of high-strength bolts and cables with lagging grouting support
technology, and field tests were carried out. The test results showed that after adopting this design, the peak value of the approaching
amount of the roof and floor of the roadway heading 80 m was 502 mm, and the peak value of the approaching amount of
the two sides was 397 mm, the deformation of the roadway was effectively controlled, and the stability of the roadway was effectively ensured.
Key words: abnormal stress; soft rock roadway; lagging grouting
