摘要
由拟建厂房与采空区地表交互作用进行地表二次沉陷判别,按随机介质理论进行地表沉陷及二次沉陷的变形计算,再综合由下伏大断层、地质陷落柱、地震等引起的附加开采沉陷影响,得出厂房南侧小煤矿北界南移90m,采取系列化基础结构的强化与预调整措施后,可以建厂的技术结论。实施资源调换以调整开采边界、采取系列结构基础措施后,厂房建成并安全生产多年。
The secondary sinking of earth surface is determined based on the study of interaction between building on earth surface and mining cavities in the ground.The deformation of earth surface is predicted with random-medium theory.Finally considering additional factors,such as large subsiding fault,geological cave-in pillar,and earthquake,the technology decision on electrolysis aluminum factory building on earth surface with mining cavities below is made.The factory building has been kept safe for several years.
