In the open pit mine, the slope stability is a serious threat to the safety of mine production, so it is very important to strengthen the deformation monitoring and stability analysis of high and steep slope. This paper taking the northern slope of an open pit mine in Yunnan as an example, applied close range photogrammetry technology to the open pit mine slope deformation monitoring, compared and analyzed photogrammetry solution calculated data with the total station monitoring data, and obtained that it is feasible to apply the method of close range photogrammetry application to open pit slope deformation monitoring. Then it analyzed the factors that affect the measurement accuracy, and put forward the corresponding measures to improve the accuracy.%在露天矿山，边坡稳定性严重威胁着矿山的安全生产，加强对高陡边坡的变形监测和稳定性分析就显得非常重要。文章以云南某露天矿北部边坡为例，将近景摄影测量技术应用到露天矿山边坡变形监测中，将摄影测量解算出的数据与全站仪监测数据进行了对比分析，得出近景摄影测量方法应用于露天矿边坡变形监测是可行的，然后对影响量测精度的因素做出分析，并提出提高精度的相应措施。
