青菜冲矿主斜坡道破坏变形及加固措施

Deformation of main slope in Qing Caichong mine and reinforcement measures

通过对青菜冲矿主斜坡道变形破坏原因的分析和研究，提出了主斜坡道加固方案，并成功抑制了在松软、膨胀岩体中斜坡道的变形破坏。

The plan for reinforcing main slope is proposed on the basis of analysis and study of the cause for deformation of main slope in Qing Caichong mine, and deformation of main slope in loose, soft and expansed rocks is successfully controlled.
