尾砂胶结充填法对地表建筑设施稳定性影响分析

Analysis on the Impact of Backfilling Cementation Filling Method on the Stability of the Surface Buildings

采用大型有限元模拟软件对矿山开采充填过程进行三维仿真模拟计算,数值模拟结果与现场实测数据基本相符,其地表变形的主要技术指标小于建筑物Ⅰ级变形的要求,证明采用尾砂胶结充填采矿法开采后造成的地表位移对地面建筑设施影响不大,可以保证地表建筑设施的稳定性。

Mining filling process is three dimensional simulation calculated by finite element simula- tion software. The results of numerical simulation is the same with the field measured data. The main technical index of the ruing surface deformation is less than the I level building deformation. The impact of the surface displacement after backfilling mining cemented filling mining method on the ground building facilities is not tremendous. The stability of the surface structures can be guaranteed.
