摘要
主要介绍了煤田采空区预留煤柱段路基抗变形注浆治理方案设计,通过煤田采空区对预留煤柱的稳定性影响分析,结合注浆原则,制定了路基抗变形注浆治理的设计方案以及注浆质量检测方法和施工控制措施。并以此很好地指导了乌鲁木齐外环路东北段六道湾煤田采空区预留煤柱段基坑变形注浆治理工程的施工。
This paper mainly introduced the grouting program for subgrade deformation resistance in prearranged pillar section of coal mine goaf.Through analyzing the influence of coal mine goaf on the stability of prearranged pillar,combined with the principle of grouting,the grouting program for subgrade deformation resistance as well as grouting quality inspection method and construction control measures have been established,which have guided the construction of foundation pit deformation grouting treatment engineering in prearranged pillar section of Liudaowan coal mine goaf in outer ring road northeast section in Urumqi.
