Analysis on stability of building foundation in coal mining subsidence area

The paper pointed out the conceptions of the space stability and the time stability for the foundation in the coal mining subsidence area and the four main points for the analysis on the foundation stability in the coal mining subsidence area.The paper analyzed the space relationship between the main loaded layer of the foundation and the cracking zone of the goaf,the time for mining subsidence stabilization,the calculation for the rest displacement deformation in the mining subsidence area and the influence to the foundation stability.Taking the foundation treatment and control project in the mining subsidence area of Beipiao Mining area as an example,the paper showed that the stability analysis of the foundation in the mining subsidence area applied to the treatment and control planning of the mining subsidence area.
