基于有限差分法理论,利用FLAC3D软件对阿舍勒铜矿深部采场结构稳固性进行数值模拟分析,再现了采场结构应力分布及其变形过程,掌握了采场结构介质应力分布规律和几何变形特征。数值模拟计算结果与该矿山采场结构围岩变形变化相吻合,对深部采场设计、支护方式选择和安全生产管理提供了理论依据。
Based on the theory of finite difference method, the numerical simulation analysis of deep stope structure stability in Ashele copper mine is carried out by using FLAC3D software. The stress distribution and deformation process of stope structure are reproduced, and the stress distribution law and geometric deformation of stope structure medium are mastered feature. The results of numerical simulation are consistent with the deformation and deformation of surrounding rock in stope structure of the mine, which provides a theoretical basis for the design of deep stope and the selection of support modes and safety production management.
