“…The Da Niu Di gas field (depth of 2000 m or more) overlaps with the upper Jurassic coal seam (depth of 800 m or more) in the vertical direction over a large area (Figure 1). The length of gas transmission lines, gas gathering lines, and gas gathering trunk lines laid in the region is about 40.2 km [22,23]. The surfaces of working faces in mines within the Da Niu Di gas field Processes 2024, 12, 213 3 of 22 are covered by thick alluvium aeolian sand, and the thickness of the aeolian sand is about 18 m [24].…”

In recent years, the integrity of the gas pipeline in the coal-gas co-mining subsidence area has become a critical problem, restricting the safe and efficient mining of coal resources. This paper establishes a theoretical model for the safety prediction of gas pipelines in mining subsidence areas based on elastic free theory, constructs a 3D model of pipe-sand soil by using ABAQUS simulation software (2021), analyzes the characteristics of ground surface and pipeline settlement combined with the measured data on-site, and reveals the temporal and spatial evolution law of the pipeline load and deformation under the condition of diagonal intersections of the pipeline and high-strength mining working face. The results show that during the mining cycle, the pipe and the sandy soil body experienced the stage of cooperative deformation, the stage of increasing non-cooperative deformation, and the stage of weakening non-cooperative deformation; the pipe body is most vulnerable to yield failure in the circumferential direction of 180°, 45°, 225°, and 0°; the relative deformation rate of the pipe experienced a slow and rapid increase in the stage, and tends to flatten out when the advancement length is about 1.5–2 times the distance at the taken cross-section. The study’s results are conducive to accurately predicting the pipe failure orientation under high-intensity mining conditions in coal seams, improving the diagnostic efficiency of pipes, and optimizing the advancement speed of the working face.

“…In the field of groundwater monitoring in open-pit coal mining areas, through long-term monitoring and analysis of the mining area in Riyadh, Saudi Arabia, Yihdego and Drury [15] found that open-pit mining activities in arid areas resulted in a significant drop in groundwater level. Existing articles on groundwater dynamic observation and data analysis mainly focus on urban groundwater source areas [11,12,[25][26][27][28] and underground coal mining area [29][30][31][32][33][34][35][36], there are few articles about the spatial and temporal distribution charac-teristics of groundwater, disturbance range, and factors under the condition of high-intensity mining in open-pit coal mines, and the distribution of the diving ecological groundwater level needs to be further studied.…”

Groundwater distribution influenced by mining activities is hard to be tracked due to the lack of accurate and real-time monitoring data. To address the groundwater dynamic change data under the mining conditions of open-pit coal mines, a three-dimensional automatic observation network of groundwater was constructed, and this observation network takes open-pit as the center, showing a radioactive distribution, based on hydrogeological conditions, and observes different aquifers. The data was analyzed by integrating hydrology, mining activity, and meteorological data. Analytic hierarchy process was adopted to reveal the underground disturbance influencing factors, and suggestions for groundwater protection were given. The results show that the dynamic variations of the groundwater with time can be divided into 3 types (precipitation affected, unaffected type, and mining affected types). The drainage operation during the open-pit mining triggered the drop of groundwater level, resulting in a cone of depression. The maximum drawdown of the central groundwater level was 60 m. And the disturbance mainly occurred in the mining area where the maximum groundwater disturbance radius was 8 km. Artificial drainage was the main disturbance factor of groundwater, and the range of groundwater level drop within the disturbance radius was closely related to the distance from the open-pit coal mine and the drainage volume. The closer the distance to the mines and the higher the drainage volume led to the deeper the groundwater level drop. This study shows the importance of the three-dimensional observation network of groundwater and provides a good reference for groundwater resources protection and ecological restoration in open-pit coal mines.
