中文摘要:
      随着工业化发展速度加快,大量采煤带来的环境污染问题日益突出。为了保护安康石煤开采区域的生态环境,掌握当地污染物运移规律尤为重要。因此,基于安康市2018年2月地下水流场资料,利用Visual Modflow中的MT3DMS模块建立溶质运移模型,对采煤厂污染易发区域的多种特征污染物在不同情况下的运移进行研究,并提出相应的污染防治建议。结果表明:当未采取任何措施时,Al3+、Fe3+和NH+4这3种特征污染物在泄漏1 000 d后超标面积在1 893~5 975 m2之间;当安装防渗层或加快检漏频率后,仅NH+4在泄漏1 000 d后出现1 693 m2的超标,其余污染物浓度均低于超标限。
英文摘要:
      With the rapid development of industrialization, environmental pollution caused by a large number of coal mining has become increasingly severe. In order to protect the ecological environment of stone coal mining area in Ankang City, it is very important to understand the local pollutant migration rules. Therefore, based on the groundwater head data of February 2018 in Ankang City, a solute transport model was established by using the MT3DMS module of Visual Modflow to study the transport of various characteristic pollutants in polluted areas of coal mining plants under different conditions and to provide the corresponding pollution prevention and control suggestions. The results showed that: the excess area of the three characteristic pollutants(Al3+,Fe3+,NH+4) was between 1893-5975 m2 after 1000 d leakage without any treatments. When the impermeable layer is installed or the leakage detection frequency is increased, only 1693 m2 of NH+4 appears after the leakage of 1000 d, and the concentration of other pollutants is lower than the level of the limit.
