摘要

目的近三十年来,露天煤矿在中国干旱和半干旱地区的开采规模不断扩大,露天煤矿的开采深刻地改变了土壤环境,对曝气带土壤水分循环产生了深远的影响。因此,本研究探讨了露天煤矿开采对中国内蒙古自治区东部半干旱草原土壤水分过程的影响。对这些土壤样品进行了稳定同位素特征({\delta ^2 H, \delta ^{18} O})和水分含量分析。结果与讨论矿区内部堆场的土壤蒸发损失明显高于草地,\({\delta ^{18} O}\)率为 22.26%,\({\delta ^2 H}\)率为 6.61%。矿区土壤蒸发的极限深度为 260 厘米,而草地为 200 厘米。矿区地下水导率的增加与土壤蒸发损失的增加有关。土壤同位素分析表明,露天采矿导致强降水时更深的优先水流入渗,矿区达到 280 厘米,而草地为 220 厘米。这项研究全面了解了露天采矿对半干旱地区土壤水分含量、蒸发和渗透的影响,为生态复垦和可持续矿山建设提供了重要启示。

Alterations in soil moisture dynamics due to open-pit coal mining semi-arid regions: Perceptions based on soil water stable isotopes and underground water conductivity analysis

Purpose

Over the past three decades, open-pit mining has been expanding in arid and semi-arid areas of China.Open-pit mining profoundly changes the soil environment and has a profound impact on the circulation of soil water in the aeration zone.Therefore, this research explores the impacts of open-pit coal mining on soil moisture processes in the semi-arid grasslands of Eastern Inner Mongolia Autonomous Region, China.

Materials and methods

Soil samples were collected from depths of 0–500 cm at Shengli No. 1 open-pit mine’s inner dump and a nearby natural grassland. These soil samples were analyzed for stable isotope characteristics (\({\delta ^2 H, \delta ^{18} O}\)) and moisture content. Collection of underground water samples inside and outside the mining area for conductivity analysis.

Results and discussion

Soil evaporation loss in the mine’s inner dump was significantly higher than in the grassland, with rates of 22.26% for \({\delta ^{18} O}\) and 6.61% for \({\delta ^2 H}\). The limiting depth of soil evaporation at the mine was found to be 260 cm, compared to 200 cm in the grassland. The increased underground water conductivity in the mine area was linked to heightened soil evaporation loss. Isotopic profiling of the soil indicated that the open-pit mining led to deeper preferential flow infiltration during heavy precipitation, reaching 280 cm in the mine area versus 220 cm in the grassland.

Conclusions

The surface soil moisture content (SMC) increased due to mining activities intensified water-heat exchanges with the atmosphere, leading to more frequent and severe wet-dry cycles. This study provides a comprehensive understanding of open-pit mining’s impact on SMC, evaporation, and infiltration in semi-arid areas, offering critical insights for ecological reclamation and sustainable mine construction.

期刊介绍: The Journal of Soils and Sediments (JSS) is devoted to soils and sediments; it deals with contaminated, intact and disturbed soils and sediments. JSS explores both the common aspects and the differences between these two environmental compartments. Inter-linkages at the catchment scale and with the Earth’s system (inter-compartment) are an important topic in JSS. The range of research coverage includes the effects of disturbances and contamination; research, strategies and technologies for prediction, prevention, and protection; identification and characterization; treatment, remediation and reuse; risk assessment and management; creation and implementation of quality standards; international regulation and legislation.
