摘要
阐述了金属矿山井下采空区的特点,通过对采空区的现场调查,用FLAC-3D软件模拟某铁矿坑内矿房回采后的采空区应力分布情况及影响.根据模拟结果分析,得出采空区的稳定性状况属于暂时稳定的结论,并预测了采空区的发展状况,为保证矿山的安全生产和采空区的治理提供科学的依据.
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.
