| Abstract: | The characteristics and stability analysis method of metal mine goaf are expounded. According to the field investigation of mined-out area of an iron mine,the FLAC-3D software are used to simulate the stopping progress to find out the distribution of stress in mined-out area and the distribution＇s effect on the stability of goal. According to the analysis result of simulation, it is concluded that the stability of the goal is temporary,and the status of development of the mined-out area is predicted, in order to provide scientific basis for ensuring the safety production of mine and the management of mined-out area. |
