%X 为探究采煤矿活动影响下,矿区浅层地下水和地表水水文地球化学特征及其成因,以中国华北地区典型隐伏型煤矿区(宿县矿区)地下水和地表水为研究对象,并通过Piper三线图、Gibbs图、自组织神经网络对研究区地下水和地表水的水化学特征及其成因进行探究。研究结果表明:1) 浅层地下水和地表水中阳离子含量变化为Na+ > Ca2+ > Mg2+ > K+,阴离子含量变化为
;浅层地下水和地表水的水质类型分别为HCO3-Ca?Na型和HCO3-Na型;Gibbs图表明岩石风化作用是影响研究区浅层地下水和地表水水化学特征的主要因素;2) 相关性研究表明:Na+、Mg2+、
之间存在正相关,说明这些离子可能来源于碳酸盐矿物的溶解;F-与Ca2+存在负相关性,表明F-可能来源于萤石等含F-矿物;3) 自组织神经网络识别出自然作用、农业面源污染和人类活动干扰是影响研究区水体水化学特征成因的因素。
In order to explore the hydrogeochemical characteristics and causes of groundwater and surface water in the mining area under the influence of coal mining activities. Taking the groundwater and surface water of the typical hidden coal field (Suxian mining area) in North China as the research object, the hydro-chemical characteristics and causes of the groundwater and surface water in the research area are explored through the Piperdiagrams, Gibbs diagrams, and self-organizing map. The results show that: 1) The change of cation content in shallow groundwater and surface water is Na+ > Ca2+ > Mg2+ > K+, and the change of anion content is
; the water quality types of shallow groundwater and surface water were Ca?Na type and HCO3-Na type respectively; Gibbs diagram shows that rock weathering was the main factor affecting the hydro-chemical characteristics of shallow groundwater and surface water; 2) the correlation study shows that there was a positive correlation between Na+, Mg2+,
, which indicates that these ions may come from the dissolution of carbonate minerals. There was a negative correlation be-tween F-and Ca2+, which indicates F- that may come from F- containing minerals such as fluorite; 3) The self-organizing map identified that natural action, agricultural non-point source pollution and human activities are the factors which affect the water chemical characteristics in the study area.
