“…In the process of resource extraction, the sharp increase in mining drainage and production water and mining ground fractures can lead to a significant drop in the groundwater level, thus causing ecological, environmental, and social problems such as the death of surface crops, the reduction of vegetation, and difficulties in water supply for humans and animals [5][6][7][8][9][10]. At the same time, the extraction process causes the movement, deformation, and discontinuous destruction of rock layers and ground, triggering surface deformation accompanied by ground collapse, ground cracks, landslides, and other serious geological disasters [11].…”

Along with the accelerated shift of coal mining to the ecologically fragile west, the contradiction between coal resource development and ecological protection in the western arid and semiarid coal mining areas is rapidly intensifying. Based on the above background, this thesis takes the coal mining area in the arid and semiarid regions as an example; applies the theories of ecology, coal mining subsidence, geodesy, and ecological restoration; uses remote sensing in synthetic aperture radar (SAR), geographic information system (GIS), and mathematical modelling to reveal the ecological evolution law of the mining area; measures the ecological damage of the mining area; and then proposes a reasonable ecological restoration strategy. The surface deformation monitoring study in the study area shows that on the whole, some areas in the study area have different degrees of surface subsidence disasters, and the maximum surface subsidence value exceeds 800 mm. From the distribution of surface subsidence in the study area, surface subsidence disasters mainly occur in the eastern and central mountainous areas rich in coal resources, as well as in the mining areas west of the Yellow River, and the subsidence basins are distributed in a series of irregular concentric ovals. In terms of the scale of surface subsidence in the study area, a total of 230.03 km2 of land in the study area showed surface subsidence hazards during the monitoring period, accounting for 13.78% of the total area of the study area, of which the area of severe subsidence was 44.98 km2 (2.69%). The area of more serious subsidence area is 101.33 km2 (6.07%), and the area affected by subsidence is 83.72 km2 (5.01%).

“…With the continuous expansion of resource exploitation, open-pit mining has gradually shifted to large mining depths and steep slopes, while the contradiction between output and instability of slope rock masses has highly increased (Tao et al 2021). From 2007 to 2017, the accidents due to slope stability were 221 contributing to 31% of all open pit accidents and the major cause of accidents in Indian open pit mines (Satyanarayana and Budi 2019).…”

High and steep layered rock slopes with upper steep and lower gentle style is a typical layered rock slope in Western region of China. Deformation regulations and failure mechanism of this kind of slope induced by step-by-step excavations were investigated in this study. By FLAC3D, excavation process is simulated according to actual situation (the first three phases) and planned excavation order (the last two phases). For the first three phases, through comparing simulation results and actual slope form, rationality of the model has been checked. For the last two phases, failure characteristics have been analyzed by simulation results. During the whole process of excavation, deformation can be summarized as "slip-bend-shear", and most dangerous slip surface of composite-style has been developed gradually into the slope. This research can provide theoretical support and guidance for the stability analysis, quantitative excavation design and pre-warning system of this type of slope in the process of western development in China.
