“…Eqs (15)(16)(17) describe the whole process of the change of resistivity with seepage and fracture development during the slope from drying to saturation. It can be seen from Eq (15) to Eq (17) that the resistivity of the water bearing slope is positive correlation with the proportion of residual air, is negative correlation with the water content in the pores of the slope, which is consistent with the conclusion of Archie formula.…”

In order to investigate the seepage law and crack development characteristics of dump slopes, as well as the impact on slope stability during drying and wetting cycles, a simulation test slope system was constructed in a rainfall environment, specifically designed to mimic the engineering conditions of dump slope. The apparent resistivity response formula for the seepage and crack development processes was derived based on the three-phase medium theory of rock-soil bodies and Maxwell’s conductivity formula. The geoelectric field characteristics pertaining to slope damage and the corresponding patterns of alteration were comprehensively investigated. The results demonstrate a negative correlation between resistivity and slope water content, with resistivity increasing as cracks develop and decreasing with water infiltration. The progression of crack formation in a rainfall environment on a dump slope can be categorized into three stages: The initial phase involves the saturation of the slope as water content increases. Subsequently, the second phase entails the initiation and expansion of capillary zones, along with the formation of dominant waterways. Lastly, the third phase encompasses the formation and expansion of cracks within the dumping site. The occurrence of sudden changes and abnormal fluctuations in apparent resistivity within a saturated slope signifies the presence of cracks and weak surfaces, leading to gradual and irreversible damage. This phenomenon serves as an indicator of slope damage and can be utilized for the early prediction of slope instability.

In open-cast mines, a dump stability analysis is tedious for engineers. In the past, dump slope disasters have caused a loss of human resources and mining machinery. Sometimes, the machinery is stuck in a debris flow. Therefore, Susceptible Zone Identification (SZI) and its treatment are essential for the mining industry. This study aims to identify multiple failure zones in a large dump using a Multi Model Optimization (MMO) technique. Realistic 3D modelling is essential for accurate stability evaluation. Researchers have used 2D numerical modelling for dump slope stability analysis in many studies. However, the geometry of mine dumps is irregular because of unplanned Overburden (OB) material deposition. If the real 3D geometry of the dump is not considered, the slope stability results may confound researchers. Therefore, this study aimed to analyze the stability of the Sonepur Bazari mine dump with multiple failure zones using realistic 3D modelling. The Limit Equilibrium Method (LEM) and Finite Difference Method (FDM) were employed for slope stability analysis. This study investigated different critical zones in the entire dump. The advantage of this combined approach is that large internal and external dump failure zones can be quickly identified, and decisions can be made for mitigation.

“…Absolute localization was successfully achieved by integrating 3D local ground Lidar data with global 3D aerial data (Vandapel et al, 2006). UAVs were found to be invaluable for slope mapping and hazard assessment based on slope angles within geotechnical engineering (Zolkepli et al, 2022) (Layek et al, 2022). Furthermore, they were recognized for their efficiency in generating Digital Terrain Models to serve various purposes (Giordan et al, 2020).…”

Abstract. This study presents a novel method for high-altitude terrain following photogrammetric mapping using Unmanned Aerial Vehicles (UAVs) that adapt their height to the terrain's morphology. Traditional grid missions in UAV mapping surveys use nadir photographs to cover an area of interest which is taken from a fixed height from the datum.Many times this leads to difficulties in flight mission and processing when hilly/undulated terrain is under consideration. The proposed solution addresses this by adjusting the UAV's flying height based on real-time terrain information gathered by a range detection sensor. This paper tests the proposed method in a hilly area in the Himalayas, capturing high-resolution images and processing them using UAV-based photogrammetry software. The pre-acquired terrain information ensures safe separation from obstacles and enables trajectory generation at lower altitudes when planning initial flights. The experimental results validate the effectiveness of the proposed method and highlight its potential for generating high-resolution photogrammetric products applicable to various UAV mapping tasks and monitoring scenarios. Overall, this research contributes to advancing the field of UAV mapping by providing a practical and effective solution for UAV based surveys in hilly and undulated terrains. The findings of this study have significant implications for various applications, including land surveying, environmental monitoring, landslide mapping and other scenarios that require detailed and accurate data acquisition from UAVs.
