摘要
采用 2D -FLAC软件 ,依崩落法工艺流程建立地下开采地表变形动态分析模型。金山店铁矿余华寺矿区计算结果表明 ,在 - 1 5 0m水平以上开采时移动角和崩落角比较小 ,继续开采时变形趋于平缓 ,找到了影响地表变形的主要因素 ,指出矿山深部开采应该注意的问题 。
D-FLAC software was used to establish the model for dynamic analysis of the ground deformation caused by underground mining, which was based on the technological flowsheet of caving method. The calculation results for Yuhuashi mining area at Jinshandian Iron Mine showed that mining at above -150 m level had small movement angle and caving angle and the deformation would become gentle when mining continued. The main factors affecting the ground deformation were found, the points needing attention in deep mining pointed out and the suggestions on geological disaster prevention made.
