摘　　要：浅层地下工程过采(动)空区时面临采动安全隐患,文中结合采空区上方拟建的平姚输煤通道浅层地下工程项目,分析了通道采动损坏机理,认为其损坏主要以纵向水平变形产生的拉伸变形为主,并参照规程设定了其最大变形允许值。在此基础上,评价了该工程的稳定性,提出了相应的井下开采和抗变形保护技术措施,为该类地下工程的稳定性分析与抗变形设计提供了科学依据。It faces Mining security risks when shallow underground works ( action) had adopted Area. In the paper, the author analyzes Channel mining damage mechanism combining Ping Yao coal handling channel shallow underground engineering projects above the goaf, and thinks the damage mainly to the longitudinal horizontal deformation of the tensile deformation, and sets the maximum deformation allowable value reference the procedures. On this basis, the author evaluates the stability of the project, provides the measures of underground mining and resistance to deformation protection technological, and provides scientific basis for the stability of such underground works and resistance to deformation design.
