Abstract

Abstract

In this paper, the analysis of waste cave stability accord to Changing in the relationship between overlying rock & surface movement deformation and time,when the coal seam was mined, And simulation ground deformation using of FLAC3D after ground building load on, Determine the scope needed to deal with; On the basis of building load size and important degree, Using different grouting treatment countermeasures. Through monitoring data analysis about the goaf of overlying rock subsidence and building subsidence, Evaluation of the treatment effect.
