摘　　要：针对立井井壁的破坏机理 ,提出了修复治理破裂井壁的设计原则 ,同时给出了破裂井壁注浆参数的确定方法、表土层沉降量的计算方法以及卸压槽和槽钢加固结构的设计方法。应用该研究成果已成功地修复治理了 15个破裂井壁 。As for the failure mechanism of the mine shaft liner, the paper provided the design principles of the mine shaft failed liner repair and treatment and also provided the settled method of grouting parameters for failed mine shaft liner, calculation method of overburden settlement value, and the design method of reinforcement structure with pressure released chamfer and H steel. This results have been successfully applied to the repair of 15 mine shaft failed liners. The practices showed the achievements reliable.
