“…e use of numerical simulations fused with monitoring techniques has been the main research method for open pit slope stability analysis. e slope of the open pit mine is accompanied by the open pit mine from the beginning to the end, the depth of the open pit mine increases further, the height of its slope also increases further, and the risk of landslides and other instability is also increasing year by year [1][2][3][4]. As the instability of open pit slopes can endanger the lives of workers and cause property damage, it is of practical importance to study the stability of open pit slopes.…”

In this paper, the slope of the open pit of Dahongshan iron ore mine in Yunnan is taken as the research object, the safety coefficient and settlement values of the slope under natural and rainfall conditions are derived by the finite element software Midas/GTS, and the surface settlement versus time is produced by fusing the InSAR monitoring results of the study area for a whole year to judge the stability of the open pit slope. The results show that the settlement and deformation areas shown by numerical simulation and InSAR monitoring results are consistent; the comparison between InSAR monitoring results and rainfall intensity shows that the cumulative value of slope settlement has a high correlation with heavy rainfall. The safety coefficients of the slopes of the open pit under natural conditions and rainfall conditions are 1.50 and 1.21, the cumulative value of settlement in InSAR monitoring data for one year is 18.4 mm, and no obvious large deformation area is found. The use of numerical simulation combined with InSAR monitoring can realize the analysis of the stability of the slope of the open pit mine.

“…However, the limitations of the analytical models and the increase of the computational power during the last decades have made numerical analysis the primary tool for stability evaluation of open-pit mining (e.g. Cała et al 2020;Ozbay and Cabalar 2015;Steiakakis et al 2004). The weak zone's importance is discussed in many studies, but its effect on stability has not been rigorously examined.…”

Coal and lignite (brown coal) are geo-resources that have been governing energy production for decades. Geomechanical challenges, particularly slope stability, related to surface coal and lignite mines are critical during operation and will also determine the post-coal era for these areas. Several failure incidents (landslides) have been reported in mining areas, typically associated with a sub-horizontal failure surface on a weak -clay or marl -layer or an interface of low strength. This weak zone controls the soil profile in terms of stability and is common in several mines globally. In this work, this soil profile is analysed in terms of slope stability through the probability of slope failure; such a systematic analysis is currently missing from the literature. Initially, several numerical issues are addressed in the simulation of the problem. Moreover, the essential parameters' effect is examined: the height and the inclination of the slope, the inclination, thickness, and strength of the weak zone, and the strength of the overburden soil. Their effect on slope stability is evaluated by combining the probabilistic point estimate method with the finite element method and the shear strength reduction technique. This work can support a preliminary slope stability analysis and expands the knowledge and understanding of slope stability of a weak zone soil profile. It is concluded that in the presence of a weak zone, the inclination and strength of the weak zone and the water conditions are the most critical parameters and control the stability. Article highlights• Slope stability is performed on a soil profile with a weak zone, describing a common type of coal mines' failure in several countries. • Numerical issues of practical importance are addressed on the simulation and analysis of the problem. • The inclination and shear strength of the weak zone together with the water conditions control the stability of the mines' slopes.

“…High value of non-ferrous metal ores technologies for the development of metals and iron ores have much in common both in terms of the range of engineering and geological conditions, and in their development provides for the use of expensive landslide measures, while in the conditions of iron ore quarries they may be economically impractical, etc. An increase in the volume of open-pit mining operations is associated with a number of features of ensuring the stability of slopes [5,6]. Among them are the following: -increase in economically feasible depths of open works; -the interdependence of slope stability with the development system and the mining regime; -the need to change the parameters and configuration of slopes during the operation of quarries; -determining influence of technological factors; -maintaining the slopes of the sides of the quarry in a stable state; -creation of normal working conditions for mining and transport equipment.…”

Study on the influence of the deformation zones of the quarry sides on the rock mass movement

et al. 2021

The article presents a study and analysis of the causes of deformation of the slopes and sides of the quarry indicates that the magnitude and nature of the deformation processes depend on the height of the ledge, the angle of slope of the slopes, the physical and mechanical properties, the lithological and structural features of the instrument array and the geodynamic activity of the fault zones. The influence of the deformation zones of the sides of the quarry on the transport of rock masses is justified. The zone of deformed masses of the ore deposit, which affect the movement of the rock mass, is studied. Each process performed in open pit mining is linked to another workflow. Without ensuring the safety of mining operations and performing the tasks set is impossible. Transportation of rock masses in the lower horizons of a deep quarry is one of the main tasks of the industry. At the same time, the removal of deformation and landslides in the area where the transport berm is being constructed for draining and continuous transportation is the main goal of the quarry. The stability of the transport berm depends directly on the stability of the side of the quarry. It is determined that the choice of a single-lane or twolane transport berm constructed for heavy-duty quarry dump trucks depends on the condition of the side of the quarry.
