摘要
哈尔乌素露天煤矿内排土场面临排弃增高问题。分析了内排土场存在的安全隐患,通过数值模拟内排土场边坡可能存在的破坏模式,研究了内排土场承载高度与稳定性关系,边坡角与稳定性关系。
The inner dump of Ha＇erwusu Open-pit Mine faces the problem of increase. The article analyzes the safety hidden danger of the inner dump, researches the relationship between load height and stability of inner dump and the relationship between the slope angle and stability through the possible failure mode of the numerical simulation inner dump slope.
