中文摘要:
      为了从地学的角度探索一种从源头变被动为主动的废弃煤矿山矿井酸水防治的途径,指导矿山环境恢复和治理,研究工作通过建立废弃煤矿山地下水系统物理模型,模拟了不同环境条件下矿井酸水形成和演化特征、探索了不同水动力条件下的矿山酸性水pH值、电导率等指标的变化趋势。实验结果表明:通过人为工程干预,促使“采空区”氧化环境向还原环境转变,可以缓解矿井酸性水的形成;抬高系统中地下水径流带高程,将模拟矿坑中地下水径流带改变为滞留带,系统排泄水的pH值显著提高,水质得到了有效的改善。实验成果为废弃煤矿山酸性矿井水地学治理理论提供了技术支撑,也可以作为废弃矿山矿井酸水治理工作的借鉴。
英文摘要:
      In order to explore the way to treat acid water from the source of abandoned coal mine mountain mine from the geosciences point of view,guide the restoration and management of mine environmentBy building the physical model of abandoned mine mountain underground water system,it simulates the formation and evolution characteristics of mine acid water under different environmental conditions,and explores the change trend of mine acid water pH,conductivity and other indicators under different environmental conditionsThe experimental results show that the formation of acidic water in mine can be alleviated by artificial engineering intervention to promote the transformation of the oxidation environment of the “empty area” to the reduced environmentRaising the elevation of groundwater runoff zone in the system changes the groundwater runoff zone in simulated pits to a residual zone,the pH of the system excretion water is significantly improved,and the acidic water is effectively treatedThe experimental results provide technical support for the theory of water geoscience management of acidic mine in abandoned coal mines,and can also be used as a reference for the treatment of acid water in abandoned coal mines
