摘要

    摘要
  • 摘要: 随着浅部煤炭资源枯竭及国家供给侧结构调整，我国闭坑矿井数量呈逐年增加趋势。矿井闭坑后停止抽排地下水，地下水位不断回升直至与区域地下水位平衡，会对邻近生产矿井产生威胁。以淮北闸河矿区岱河煤矿为研究对象，利用Visual MODFLOW软件对矿井闭坑后水位动态回升过程进行了预测分析。研究结果表明：矿井闭坑后，随着时间延长地下水位逐步回升，回升速度前期较快，后期减慢，揭示出区域地下水径流场对矿井水位回升具有明显的影响，得出了水位随时间动态变化过程，地下水回灌时间约2 000 d，研究结果为邻近生产矿井防治老空水提供了依据和参考。
    Abstract: With the depletion of shallow coal resources and the adjustment of state supply structure, the number of closed mines in China is increasing year by year. Groundwater will not be drainaged any more after coal mine is closed. The groundwater level keeps rising until it is balanced with the regional groundwater level, and this may pose a threat to the adjacent active coal mines. Daihe coal mine located at Huaibei mining area was taken as a research target, and visual MODFLOW software was used to research the groundwater rebound process. Results show that as time goes on, the groundwater level rises gradually, and the rate of recovery is faster in the early stage and slower in the later period, revealing that the regional groundwater flow field has a significant impact on the recovery of the water level of the mine. The dynamic change process of water level with time was obtained, and the recharge time of groundwater needed about 2 000 days. The research results provide a basis and reference for the prevention and control of goaf water in adjacent active mines.
