针对唐洞煤矿-200m井底车场返修工程，通过对岩变形情况与破坏特征的现场调查与观测，分析了巷道破坏原因，提出锚、网、喷、注、锚索联合支护方案，并现场监测修复加固工程实施效果．实践表明：锚、网、喷、注、锚索联合支护可有效限制围岩的变形，提高围岩支护体的共同承载能力，本支护方案设计合理，对类似破坏巷道的修复具有一定指导作用．

According to the bottom repair engineering of Tangdong coal mine under 200 meters, this paper explores the deformation conditions and the destruction features of the surrounding rock, analyzes the reasons of the destruction, proposes a combined supporting technology scheme of anchor, nets, spray, note and anchor rope, and examines the implementation effect of the repair engineering. Practice shows that anchor, nets, spray, note and anchor rope combined support can limit file deformation of the surrounding rock, improve the joint bearing capacity of the support of the surrounding rock. The repair scheme of the support is reasonable in design, thus it plays a guiding role in the practice of roadway repairing.
