| 中文摘要 |
| 矿区水资源是维持采矿活动正常运转和支撑周边居民生产生活的重要基础,合理利用与保护水资源对矿区生态安全及可持续发展具有重要意义. 选取黄河几字弯煤炭集中开采区的地表水和地下水为研究对象,基于2023年9月采集37组水样水化学测试结果(其中地下水24组,地表水13组),利用数理统计、Piper三线图、Gibbs图、离子比值、混合模拟及PCA-APCS-MLR源解析等方法,探究黄河几字弯煤炭集中开采区地表水与地下水化学特征及控制因素,并定量解析水化学组分来源. 结果表明,研究区整体水环境呈弱碱性,地下水以淡水为主,地表水以微咸水及淡水为主;研究区地下水以HCO3-Ca型和HCO3-Na型为主,地表水以Cl·SO4-Na与HCO3·Cl-Na型为主;地表水和地下水水化学形成过程以岩石风化溶解及阳离子交换作用为主,其中,硅酸盐岩风化溶解占据主导地位;混合模拟中地下水的水化学组分含量低于地表水,混合后对地表水水化学组分含量产生稀释作用;PCA-APCS-MLR源解析确定了3个主控因子,即溶滤-富集因子、原生地质因子和人类活动因子,其中,溶滤-富集是水化学形成的首控因子. 分析结果可为矿区水资源合理开发及利用提供科学依据. |
| 英文摘要 |
| Water resources in the mining area are an important foundation for maintaining the normal operation of mining activities and supporting the production and life of the surrounding residents, and the rational utilization and protection of water resources are of great significance to the ecological safety and sustainable development of the mining area. Surface water and groundwater in the centralized coal mining area of the Yellow River's Jizi Bend were selected as the research objects. Based on the results of hydrochemical testing of 37 sets of water samples collected in September 2023 (24 sets for groundwater and 13 sets for surface water), mathematical statistics, Piper's trilinear diagram, Gibbs' diagram, ion ratio, mixing simulation, and PCA-APCS-MLR source analysis were utilized to investigate the chemical characteristics and controlling factors of groundwater and surface water in the centralized coal mining area of the Yellow River at several bends and to quantitatively analyze the sources of the hydrochemical components. The results showed that: the overall water environment in the study area was weakly alkaline, groundwater was dominated by freshwater, and surface water was dominated by brackish water and freshwater. Groundwater in the study area was dominated by HCO3-Ca type and HCO3-Na type, while surface water was dominated by Cl·SO4-Na and HCO3·Cl-Na type. The hydrochemical formation process of surface water and groundwater was dominated by water-rock action and cation-exchange action, in which the weathering and dissolution of silicate rocks dominated. The water chemistry of groundwater in the mixing simulation was lower than that of surface water, and the mixing had a diluting effect on the water chemistry of surface water. PCA-APCS-MLR source analysis identified three main controlling factors, namely, the dissolution-filtration-enrichment factor, primary geologic factor, and human activity factor, among which, the dissolution-filtration-enrichment factor was the first controlling factor for the formation of water chemistry. The results of the analysis can provide a scientific basis for the rational development and utilization of water resources in the mining area. |
