摘要
根据监测资料,分析了榆阳煤矿矿井水的来源、矿井水与煤层顶板各含水层地下水的化学成分特征、矿井涌水通道特征、不同含水层地下水对矿井水的"贡献"率,研究了红石峡水源地补给来源,探讨了榆阳煤矿开采对红石峡水源地的影响,提出了榆阳煤矿开采对红石峡水源地影响不大的结论,但由于红石峡水源地范围内煤矿较多,众多煤矿大范围、高强度开采将直接影响红石峡水源地补给来源。
By analyzing monitoring data, the water resource of wells in Yuyang mines, chemical components of well water and groundwater stored in aquifers on the roof of coal layers, features of well-gushing water passage and the ratio of groundwa-ter from different aquifers in the total amount of well water are studied. Based on these results, the source of groundwater re-charging and the influence of Yuyang Coal Mine exploitation on water resource of Hongshi gorge are researched. Results indi-cate that coal mine exploitation has little influence on the water resource of Hongshi gorge but wide range and high intensive ex-ploitation will affect groundwater recharging directly because of the relative large amount of coal mines in this region.
