摘要
在详细调查了矿山巨大复杂群采空区分布状况的基础上,建立了与其赋存状态相近的三维数值模型,运用FLAC3D软件进行数值模拟计算并获得结果。根据应力、位移和塑性区的分布规律,对采空区的稳定性进行了深入的分析研究,揭示了稳定性较差采空区的成因并明确了存在安全隐患的区域,由此提出了合理规划充填顺序、加固原生矿柱、增加人工矿柱和建立三维实时监测网的综合治理措施,保障了矿山的安全生产。
Based on the survey of the huge complicated goaf group distribution in the mining area, a three-dimensional numerical model which had similar shape with goal group was established. The FLAC3D software was used for numeri- cal simulation calculation and the results were obtained. Ac- cording to the distribution law of the stress, displacement and plastic area, the stability of goaf was studied in detail, the causes of poor stability for goal were revealed and the potential safety hazard areas were determined. Thus the comprehensive treatment measures were proposed including the reasonable planning of the filling sequence, the reinforce- ment of the original pillars, the new increase of artificial pil- lars and the establishment of 3D real-time detection system, so as to ensure the mine safety production.
