“…These techniques are therefore used in numerous types of cartographic application, from military and regional small-scale maps, to that of medium-and large-scale technical maps (topographic, geological, geomorphological, land use, etc.). Airplane/satellite photogrammetry is very useful in regional engineering-geological mapping and for detecting landslide related geomorphic landforms (Wolter et al, 2016;Mantovani et al, 2016, Clayton et al, 2017. Donati et al, 2017.…”

“…Brittle fracturing of intact rock can contribute to the evolution of rock slope instability by allowing the formation of continuous failure surfaces [6,7]. The instability of rock slopes is also enhanced by endogenic and exogenic factors, such as earthquakes [8], groundwater fluctuations [9], glacial retreat [10], and slope erosion and steepening [11]. It is clear that a comprehensive rock slope characterization is required to identify the factors controlling stability, and to investigate how their potential impacts vary both spatially and temporally [12].…”

The stability and deformation behavior of high rock slopes depends on many factors, including geological structures, lithology, geomorphic processes, stress distribution, and groundwater regime. A comprehensive mapping program is, therefore, required to investigate and assess the stability of high rock slopes. However, slope steepness, rockfalls and ongoing instability, difficult terrain, and other safety concerns may prevent the collection of data by means of traditional field techniques. Therefore, remote sensing methods are often critical to perform an effective investigation. In this paper, we describe the application of field and remote sensing approaches for the characterization of rock slopes at various scale and distances. Based on over 15 years of the experience gained by the Engineering Geology and Resource Geotechnics Research Group at Simon Fraser University (Vancouver, Canada), we provide a summary of the potential applications, advantages, and limitations of varied remote sensing techniques for comprehensive characterization of rock slopes. We illustrate how remote sensing methods have been critical in performing rock slope investigations. However, we observe that traditional field methods still remain indispensable to collect important intact rock and discontinuity condition data.

Mining under an open pit slope results in the collapse and slide of the slope. In this paper, a combination of methods including Google Earth and field investigations is applied to investigate the process of eastern slope failure induced by underground mining in the Yanqianshan Iron Mine over five years. According to the observed ground deformation features, the geomorphic zone of the eastern slope can be divided into four regions (caved rock zone, cracking zone, toppling zone, and sliding zone). Break angles and fracture initiation angles at different times are counted separately. Based on the above work, the process of initiation and development of slope failure is studied. The analysis results show that the process of slope failure could be chronologically divided into three stages. First, a collapse pit, caused by the falling of the overlying strata above the goaf, appeared on the eastern slope. Then, the rock mass around the collapse pit slid into the pit to form a small landslide. Finally, because of mining disturbances and rock creep, a large landslide occurred on the northeastern phyllite slope. The control mechanisms of each failure stage are discussed separately. Finally, the RFPA3D code is employed to simulate the slope failure process under the influence of underground mining. The results are consistent with the field observations, which provided information on deformation failure and the mechanics of the slope that could not be directly observed in the field and deepened the mechanism analysis.
