通过数值模拟分析，讨论堆积高度对尾砂开采边坡稳定性的影响，并通过模拟测点位移和应力的变化指导实际开采工作。研究结果表明：尾砂堆积高度是影响采池边坡稳定性的重要因素；在保证产量的基础上，尽量控制堆积高度不大于1倍干坡高度即可有效维持边坡稳定性；人员和设备不宜进入距采池边帮12倍干坡高度的范围内。

英文摘要：

In this paper, the effect of slope stability on the stack height of railings mining was discussed. The effect of stack height on the slope stability of tailings mining was dis- cussed by numerical simulation, and displacement and stress variation of measuring points were simulated to guide practi- cal mining. The results showed that as an important factor of mining slope stability, the stack height of railings should be less than 1 times height of the dry slope to maintain the slop stability, on the basis of ensuring efficient production. And personnel and equipment should stay the distance of 12 times height of the dry slope away.
