为了确保小煤窑采空区上方建设大型建筑物的安全,采用采空区注浆处理地基的方法,解决了建设场地发生突发性沉降变形的问题;对该场地工后地表残余沉陷变形进行了计算,提出了建筑物安全监控技术措施和抗变形技术措施。结果表明:通过对采空区进行地基注浆处理和建筑安全保护技术措施的方法,可满足大型建筑在采空区上方建设的要求。

In order to ensure the safety of large buildings built above the goaf of small coal mines, the method of grouting the goaf to treat the foundation is adopted, which solved the problem of sudden subsidence and deformation of the construction site; The ground surface residual subsidence deformation of the site after construction is calculated, and building safety monitoring and anti deformation technical measures are proposed. The results indicate that the methods of foundation grouting treatment and building safety protection technical measures for the goaf can meet the requirements of large buildings construction above the goaf.
