摘要
为科学评价霄云煤矿水质,选取了16个砂岩水样,根据8个水质指标进行水质评价。通过主因子分析、变异系数熵权法、正态云模型对霄云矿区水质进行评价,利用SPSS软件,采用主因子分析从8个水质评价指标中提取出SO42-、总硬度、Cl-、F-四个指标作为水质评价主控指标;在此基础上,通过变异系数法与熵权法综合确定指标权重,利用Matlab建立正态云模型得出霄云矿区各水样水质隶属度,确定矿区水质等级。结果表明:霄云矿区水质总体污染较严重,主因子-正态云模型评价结果更为客观地反映了矿区水质特征,采用该模型对矿井水水质进行综合评价能为矿井水环境治理提供一定的理论依据。
To scientifically evaluate the water quality of Xiaoyun Coal Mine,16 sandstone water samples were selected and evaluated based on 8 water quality indicators.The water quality of Xiaoyun mining area was evaluated through principal factor analysis,coefficient of variation entropy weight method,and normal cloud model.SPSS software was used to extract SO42-,total hardness,Cl-,-and F as the main control indicators for water quality evaluation from 8 water quality evaluation indicators using principal factor analysis;On this basis,the index weights are determined by combining the coefficient of variation method and entropy weight method.A normal cloud model is established using Matlab to obtain the water quality membership degree of each water sample in the Xiaoyun mining area,and the water quality grade of the mining area is determined.The results indicate that the overall water quality pollution in Xiaoyun mining area is severe,and the evaluation results of the main factor normal cloud model more objectively reflect the water quality characteristics of the mining area.Using this model to comprehensively evaluate the water quality of mine water can provide a certain theoretical basis for the treatment of mine water environment.
