Effect of Underground Coal Mining on the Regional Soil Organic Carbon Pool in Farmland in a Mining Subsidence Area

Abstract: The soil organic carbon (SOC) pool in farmland is changing rapidly due to human activities, thereby greatly affecting the regional and global environment, as well as influencing soil fertility and crop yields. The present study investigated the effects of underground coal mining on the regional SOC pool in farmland in the Jiuli Mining Area of Xuzhou City in China as a typical coal mining region based on field sampling, chemical analysis, model construction, and spatial analysis using the software of ArcGIS.

“…The contribution of ecological benefits was 58.9%. The factors of the soil erosion rate, subsidence rate [30,65], forest and grass coverage rate, and soil and water loss management degree in the ecological benefit weights were the main factors that facilitated the ecological benefits [66].…”

“…Jiawang District, a resource-exhausted city in 2011, had been a coal producing city for a century, cumulatively generating 360 million tons of raw coal. Long-term, large-scale coal mining has destroyed surrounding cultivated land; caused ground subsidence, ponding and soil and water pollution and had significantly negative effects on the ecological environment of the mining area [33][34][35][36][37][38]. From 2010, Jiawang District began to carry out land reclamation and ecological restoration projects in the coal mining area.…”

“…These mining processes lead to the removal of soil materials that damage the ecosystem and degrade soil properties, negatively impacting the nutrient cycle. In China, these soils located near coal mining areas are typically used for the production of crops to achieve the goal of balancing needs and population growth through increased arable soils [3,4]. Shanxi Province, in the eastern Loess Plateau, is the second-biggest coal-producing region after Inner Mongolia [5,6].…”

“…In addition to the coal mining activities, the Loess Plateau soils suffer from several problems such as severe soil erosion, the fragile ecological environment, and high chemical fertilizer applications, which have led to soil degradation [4,10]. Therefore, improving farmland management and preventing the degradation of soil resources are urgent problems in the sustainable development of the ecological environment of this area.…”
