寺河二号井新建变电站采空区处理与抗变形技术实践

On the goaf disposal and deformation resistance in the newly-built substations of No.2 well in Sihe mine

浅埋采空区工程地质条件较为恶劣,长期稳定性差,给采空区上方的工程建设带来极大的安全隐患。文中结合寺河二号井变电站改造工程,开展了浅埋采空区建筑地基注浆治理研究,通过地面打钻对采空区进行注浆治理,改善了建筑地基的工程地质环境,并采用建筑物抗变形技术措施,保证了变电站改造工程的正常安全使用。

The engineering geological condition is appalling in shallow buried goafs and the long -term stability re- mains great challenges, both of which threatens the safe project constructions above the goals. The paper studies the governance of the surface drilling the injection in buildings foundations in shallow buried goafs based on the sub- station reconstruction project of No. 2 well in Sihe mine. And the surface drilling improves the engineering geological conditions and the deformation resistance of buildings ensures safe utility of the substation reconstruction.
