Emission factors of fugitive methane from underground coal mines
The construction and commissioning of large-scale surface coal mines have propelled the production capacity proportion to nearly 22%, which is more than two times that in 2015 (Wang, K. et al., 2019). Contrary to surface coal mines, underground coal mines have complex technical characteristics and mining conditions.This region has the most complicated hydrogeological conditions of China’s coal mining area, making it the most complex of China's coal mining areas. Water inrushes happen frequently, and the volumes of water inrush are considerable (2700–27,000 m 3 /h), which easily floods mines, while normal mine water inflow is still large Characteristics of Water Hazards in China’s Coal Mines: A

Effects of Underground Coal Mining on Soil Spatial Water
The impact of coal mining subsidence on surface ecology involves the influence of several ecological elements such as water, soil, and vegetation, which is systematic and complex. Given the unclear understanding of the synergistic change patterns of the water–soil–vegetation ecological elements in the influence of coal mining in the west, this In 2020, the number of coal mines producing under 300,000 tons/year was reduced to 1,129, while the average production capacity of coal mines increased to 1.1 million t/a(National Energy In JuneTransforming China's coal mines: A case history of the Shuangliu Mine

Main geological and mining factors affecting ground cracks
As one of the largest coal-rich provinces in China, Shanxi has extensive underground coal-mining operations. These operations have caused numerous ground cracks and substantial environmental damage. To study the main geological and mining factors influencing mining-related ground cracks in Shanxi, a detailed investigation was Coal is the basic resource underpinning energy generation in China, however, constant, large-scale mining of coal results in many problems such as ecological destruction of mining areas. As a result, backfilling of solid waste underground is proposed to control strata and surface subsidence and to protect the environment. At present, Properties and Application of Backfill Materials in Coal Mines in China
