摘要:
矿山闭坑后大量被污染的矿坑水对裂隙岩溶水具有潜在的影响.对陶枣煤田裂隙岩溶水水质评价发现区域内水质较差和极差级别分别占到总数的25.64%和41.03%,说明岩溶水总体水质较差.通过对岩溶水水化学特征分析得知,区内岩溶水阴离子类型有4种,分别为HCO3-型、HCO3-·SO42-型、SO42-·HCO3-型和SO42-型,阳离子可划分为Ca2+、Ca2+·Na+和Ca2+·Mg2+或Mg2+·Ca2+3类型.通过对1991至2017年水化学动态特征分析发现区内地下裂隙岩溶水受煤矿开采影响较大,基于聚类分析法发现区内主要存在2种污染途径,分别为地表水渗透污染和矿坑水串层污染.
A large amount of contaminated mine water will further affect the fissured karst water environment.This study evaluated the environmental quality of fractured karst water,the poor and extremely poor level of water quality in the area account for 25.64%and 41.03%of the total respectively,reflecting the overall poor quality of karst water.Through the analysis of the chemical characteristics of karst water,it is found that there were four types of anions in the karst water in the area:HCO3-,HCO3-·SO42-,SO42-·HCO3-,and SO42-,and three types of cations:Ca2+,Ca2+·Na+,Ca2+·Mg2+or Mg2+·Ca2+.The article analyzes the dynamic characteristics of hydrochemistry over the years from 1991 to 2017 and concludes that the underground fissure karst water in the water quality area has been worsening pollution and deteriorating water quality due to the influence of coal mining.Based on cluster analysis,it is found that there were two main pollution pathways in the area:surface water infiltration pollution and mine water cross layer pollution.
