摘要
以榆神矿区浅表层地下水长期实际监测数据记录为基础,选择典型钻孔观测记录综合分析了该区浅表层地下水区域水位动态的时空变化特征。榆神矿区浅表层地下水位年内变化幅度在0.26~2.48 m,大部分区域水位变幅在0.9~1.6 m。采用模糊聚类分析方法对榆神矿区浅表层地下水水位变化幅度类型进行划分。通过研究不同水位变幅类型区水位变化规律以及主要影响因素,浅表层地下水水位动态变化类型总体可划分为气候型、气候—开采型、工程活动—气候型3种类型,但截至目前煤炭开采活动对榆神矿区第四系浅表层地下水位影响较小,气候为最主要的影响因素。
Based on long-term actual monitoring data records of shallow groundwater in Yushen Mining Area,a typical borehole observation record was selected to comprehensively analyze the spatial-temporal changes of the groundwater level in the shallow groundwater area of the area.The annual variation of shallow groundwater level in Yushen mining area ranged from 0.26 to 2.48 m,and the water level variation in most areas ranged from 0.9 to 1.6 m.The fuzzy cluster analysis method was used to classify the types of shallow groundwater level changes in Yushen mining area.By studying the water level change laws and main influencing factors in different types of water level fluctuation types,the types of dynamic changes in shallow groundwater levels could be divided into three types:climate type,climate-mining type,and engineering activity-climate type.But so far,coal mining activities impact on the shallow surface water table of the Quaternary in the Yushen mining area was small,and climate was the most important factor.
