摘要
采用了ANSYS有限元软件对黑山露天矿北帮顺倾边坡进行变形破坏机理数值模拟,分析了北帮边坡潜在变形破坏模式和北帮边坡出现局部片帮现象的原因,针对BB1-1和BB1-2 2个工程剖面提出北帮坡削坡方案,以保障北帮总体稳定系数满足安全储备系数的要求。研究结果为矿山的安全生产提供了重要的技术保障。
The deformation and failure mechanism of the north slope of Heishan open-pit mine is simulated by ANSYS finite element software.The potential deformation and failure modes of the north slope and the causes of the local slope-slicing phenomenon of the north slope are analyzed.be aimed at BB1-1 and BB1-22 engineering sections,the slope-cutting scheme of the north slope is proposed to ensure that the overall stability coefficient of the north slope meets the requirements of the safety reserve factor.Research results provide an important technical guarantee for safe production of mines.
