摘要
大规模煤炭开采导致了地下水环境演化轨迹严重偏离天然状态的演化方向,引发了诸如地下水位下降、降落漏斗形成和扩展、水质恶化等一系列的地下水环境问题,并反作用于矿区的经济发展和居民的生产生活,使矿区陷于生态环境恶化、经济发展迟缓的境地。究其根本原因,就在于大规模煤炭开采造成了矿区含水层结构变异,进而导致了区域含水介质发生非均质性变化,最终影响了地下水循环演化态势。因此,开展含水层变异研究,揭示采煤对区域地下水环境演化的影响,显得尤其重要。以焦作矿区为例,通过野外调查、资料收集等工作,研究了采煤前后含水层环境的变化,阐明了采煤活动对地下含水层的影响。
Because of the large-scale coal mining, the groundwater environmental evolution has seriously deviated from the unaffected natural evolution, and has caused a series of problem like the groundwater-level declines, cone of depression expansion and water quality deterioration, which have acted and reacted on economic development and daily life in diggings and dragged the area into environmental deterioration. The root of the matter is the aquifer structural variation caused by large-scale coal mining. The variation made anisotropic changes on aquifer and gradually affect the groundwater environmental evolution. Therefore, based on field investigations and previous study results, the paper makes a study on the variation of aquifer environment and summaries the influence of coal mining on groundwater aquifers.
