摘要
采用FLAC3D软件对某煤矿副井井筒非采动破坏的数值渗流模拟实验分析,从而获取了"一含""二含""四含""三含"耦合作用下的井筒竖向移动规律,得出了"四含"渗流作用下的竖直移动量与应力值较大,是造成井筒破坏的主要原因之一,从而为井壁破裂及防治提供了科学依据。
By using FLAC^（3D）software,the numerical simulation analysis of seepage flow of mine auxiliary shaft in the nonmining damage condition was carried out and the vertical movement law of shaft under coupling action of four aquifers was summarized. The result shows that the vertical displacement and stress value is larger under the action of the fourth aquifer seepage,which is one of the main causes of shaft damage. The research can provide scientific basis for the mine shaft supporting.
