摘要
以淮南1某矿不同含水层水及采空区水数据为例,采用模糊评判方法对突水水源进行判别分析。结果表明:在原有Na++K+,Ca2+,Mg2+,Cl-,SO42-,HCO3-六个评判因子基础上,增加总硬度、碱度、PH值和矿化度等作为新的评判因子,其准确率由80%提高至100%。由此表明:判别准确性与样本个数没有直接关系,仅与选取样本代表性有关,选择合适评判因子是提高模糊评判可靠性。
By analyzing data about sample water collected aquifers and goafs of a coal mine in Huainan with fuzzy evaluation method , the paper makes a study on the accuracy and practicability of fuzzy evaluation method.Analysis results shows that the accuracy increase from 80 percent to 100 percent when total hardness, alkalinity, pH and salinity are added to list of evaluation factors, which has included Na＋＋K＋,Ca2＋,Mg2＋,Cl-,SO4 2-and HCO3 -.The change indicates that it is the property but not the quantity of samples affect the ac-curacy of evaluation result.Accordingly, appropriate evaluation factors will improve the reliability of fuzzy evaluation .
