| 摘 要： | 通过对露天矿排土场稳定性的研究,总结了排土场的基本破坏形式及影响排土场稳定的因素。对台阶上的集中荷载对排土场稳定性产生的影响进行了理论分析。基于该理论以及CAD的二次开发,实现了对于车辆后退排土的极限稳定位置的搜索。该系统在我国北方的两个露天矿进行了实际应用,取得了一定的效果,验证了系统的可靠性,同时为制定合理的排土方案提供了重要的依据。

| Abstract: | Through the stability study of the dump in the opencast pit, the paper summarizes the major failure modes of the dump and the factors influencing the dump stability. The theoretical analysis is carried out to study the influence of concentrated loads that appear on steps to the dump stability. Based on the theory and CAD secondary development, the paper realizes the searching of limit stable position when the truck falls back to dump material. The system has been applied to two opencast pits in north of Chi... |
