摘　　要：为了提高南芬露天铁矿2号排土场安全管理水平,本文提出了一种应用"恒阻大变形缆索滑动力监测预警系统"来监测露天矿山排土场潜在滑坡灾害的思路。这种思路的核心思想是当排土场长期自然沉降而发生位移、裂缝时,该系统能够适应松散岩体的大变形特点而不被拉断破坏,从而可以对排土场边坡失稳全过程进行加固、监测和预警;在边坡滑坡发生前和蠕动形成滑坡的过程中,该系统自动计算并绘制下滑力动态监测曲线,映射边坡稳定特征,指导生产决策部门制定防治措施。该系统在露天矿山排土场稳定性监测领域的应用,是露天矿山排土场监测历史上的一次新突破。In order to improve Nanfen open-pit iron of the 2# Dump of safety management, this paper presents an application idea that ＂constant resistance the large deformation rope slip power monitoring and early warning system＂ to monitor potential landslide hazards of the open pit mine dump. The core idea is that when the dump have displacement and cracks for natural subsidence in the long-term that system can adapt the loose rock mass that can not pulled off that deformation characteristics, which can be reinforcement, monitoring and early warning to dump slope instability; the system can automatically calculate and to draw dynamic monitoring curve before the slope landslide and the process of peristaltic to landslide, the characteristics can guide production departments to develop prevention measures. The application of the system in the open pit mine dump stability monitoring field and is a new breakthrough in the monitoring history of the open pit mine dump.
