“…In particular, in recent years, all sectors of society have paid increasingly more attention to the ecological environment, forcing enterprises to continually carry out technological innovations to fundamentally solve the problem of water resources protection and utilization, thus achieving the goal of 'zero discharge' and 'optimal utilization' of mine water (Hannan & Broz 1976;Cao et al 2019;González-Quirós & Fernández-Álvarez 2019;Li et al 2019;Zhao et al 2019;Jiao et al 2020). Underground reservoir has the characteristics of no land occupation, large storage capacity and small evaporation loss (Hannan & Broz 1976, Menéndez et al 2019Fan et al 2020;Menéndez et al 2020;Song et al 2020;Wang et al 2020a, 2020b, 2020c, Yao et al 2020Yang et al 2020). Shendong Mining Area of China took the lead in carrying out the practice of water resource preservation during mining, covering the storage, purification, and recycling of groundwater reservoir water resources, which reasonably solves the problem of coordination between ecological protection and coal mining in the mining area, and achieves significant economic and social benefits (Gu 2015;Cao et al 2019).…”

“…Previous research focuses mainly on mining-induced fractures and overlying strata activity law, etc. The purpose is to understand the impact of coal mining on water resources, so that corresponding measures can be taken to avoid or reduce damage (Wang et al 2018(Wang et al , 2020a(Wang et al , 2020b(Wang et al , 2020c. However, only by analyzing the development of mining-induced fractures and overlying strata activity law, it is insufficient to understand the impact degree of mining on water resources.…”

“…For instance, the currently proposed water-preserved mining methods and technologies have reduced mining efficiency and recovery rate to a certain extent, resulting in waste of resources; ground water storage faces such problems as insufficient water storage space, high water storage costs, evaporation waste and serious water pollution. Moreover, it is difficult to grasp the link between fracture development and aquifer destruction (Yao et al 2018;Liu et al 2019;Wang et al 2020bWang et al , 2020c. Therefore, mine water protection and utilization in mining areas in western China demand deeper analysis and exploration, and research should be conducted from the perspective of actual production and ecological water use in mining areas, thereby solving the contradiction between coal mining and water resources protection for water-scarce mining areas.…”

The role of coal mine underground reservoir(CMUR) in ‘guide storage and use’ greatly solves the problem of mine water waste. Replenishment and prediction of reservoir water sources provides an important support for the successful development of key technologies concerning CMUR. To study water replenishment for CMUR, the hydrogeological conditions of the Shendong mining area are investigated as an example. Based on the relationship between the development height of the ‘two belts’ of shallow coal seams and the relative occurrence location of aquifers, the aquifers are generalized and classified according to occurrence location. Taking Bulianta Coal Mine as the research background, a discrete element fluid-solid coupling numerical simulation model is constructed to analyze the development characteristics of mining-induced fractures after coal seam mining, and the water replenishment channel of the CMUR is determined. On this basis, analysis is made on the change law of water pressure in the aquifer, aquifuge and coal seam roof under mining action. Taking hydraulic head pressure and water velocity as the judgment basis, prediction and evaluation are made on the water replenishment capacity of CMUR. The research results can provide references for coal mine safety production and mine water protection and utilization.

“…However, the utilization rate of mine water is only 35%, resulting in a large amount of water waste [1][2][3][4][5]. The construction of underground water reservoirs in coal mines can store mine water, which can effectively alleviate the problem of the waste of groundwater resources caused by coal mining [1,[6][7][8]. Moreover, the mine water stored in the underground reservoir of the coal mine can also supply water to the surrounding areas during the dry season, which alleviates the shortage of regional groundwater resources [9][10][11][12].…”

This study analyzes the ability of coal mine underground reservoirs to protect groundwater resources. As the demand for coal mining continues to increase, the potential impact on groundwater resources around mines has become a growing problem. Underground water reservoirs, also known as coal mine underground reservoirs, have been constructed as a solution to protect water wastage in mining operations. However, there is a lack of awareness related to the ability of underground water reservoirs in mines to protect groundwater resources. In this study, we used FLAC3D software to analyze the formation process, water storage volume, and central storage location of the underground water reservoir in Zhangshuanglou Coal Mine. The results show that the damaged volume is 3.39 × 106 m3, and the groundwater resources that can be protected by coal mine underground reservoirs in the study area amount to 1.98 × 105 m3. We found that the storage capacity of underground reservoirs is more significantly affected by the extent of mining, which can be expressed as y = 49,056.44 + 255.75x + 1.46x2 (R2 = 0.995) (x ≠ 0). Additionally, the water storage location obtained through simulation can provide a reference for the construction of underground reservoir regulation and water storage projects. The results of the water quality analysis indicate that the concentrations of SO42− decreased by 42% with the closure of the mining area, and the pH also gradually converged to neutral. This highlights the significant role of underground water reservoirs in coal mines in promoting green production and protecting water resources and the environment.

“…Unfortunately, western China has been defined as an ecologically fragile zone because of the arid soils and low rainfall climate that render ecosystem restoration 2 of 19 problematic [3]. Existing studies have shown that coal mining has caused serious damage to the ecological environment in the semi-arid region, mainly including groundwater level decline [4,5], soil moisture reduction [6,7], soil structure deterioration, and vegetation degradation [8][9][10][11]. Among these, vegetation, as the most intuitive representation of environmental degradation, has always been the focus of ecological restoration in mining areas.…”

Ground subsidence is the main cause of vegetation degradation in mining areas. It is of great significance to study the effects of ground subsidence on vegetation. At present, few studies have analyzed the effects of ground subsidence on vegetation from different scales. However, the conclusions on different scales may differ. In this experiment, chlorophyll content was used as an indicator of vegetation degradation. We conducted a long-term field survey in the Lijiahao coalfield in China. Based on field survey data and remote sensing images, we analyzed the effects of ground subsidence on chlorophyll content from two scales (leaf scale and canopy scale) and summarized the similarities and differences. We found that, regardless of leaf scale or canopy scale, the effects of subsidence on chlorophyll content have the following three characteristics: (1) mining had the least effect on chlorophyll content in the neutral area, followed by the compression area, and the greatest effect on chlorophyll content in the extension area; (2) subsidence had a slight effect on chlorophyll content of Caragana korshins, but a serious effect on chlorophyll content of Stipa baicalensis; (3) chlorophyll content was not immediately affected when the ground sank. It was the cumulative subsidence that affects chlorophyll content. The difference between leaf scale and canopy scale was that the chlorophyll content at canopy scale is more affected by mining. This means that when assessing vegetation degradation, the results obtained by remote sensing were more severe than those measured in the field. We believe that this is because the canopy chlorophyll content obtained by remote sensing is also affected by the plant canopy structure. We recommend that mining and ecological restoration should be carried out concurrently, and that ground fissures should be taken as the focus of ecological restoration. In addition, Caragana korshins ought to be widely planted. Most importantly, managers should assess the effects of ground subsidence on vegetation on different scales. However, managers need to be aware of differences at different scales.
