| 中文摘要: |
| 及时、准确地判断出矿井突水水源是减小矿井损失,指导矿井防治水工作的有效手段,而此前建立的水源判别标准集,是正确判别突水水源的重要基础.通过对邢台矿水化学特征的综合分析,以水中6大常量组分(Na++Ka+,Mg2+,Ca2+,Cl-,SO42-,HCO3-)作为构建指标,同时采用Piper三线图、箱型图和聚类分析对矿井水样进行筛选,建立邢台矿水源判别标准集,并利用灰色关联度理论建立水源判别模型,对标准集进行校验.结果表明,标准集能够准确反映所属含水层的水化学特征,可作为矿井突水水源判别的背景值. |

| Timely and accurate identification of the water irrush source is an effective way to reduce mine loss and guide mine water prevention. Construction of a water irrush source standard set is an important basis before the identification. This paper makes a comprehensive analysis of the chemical characteristics of the groundwater in Xingtai Mine, which is based on six constant component (Na++Ka+,Mg2+,Ca2+,Cl-,SO42-,HCO3-).The water samples are screened by using Piper diagram, BOX plot and Cluster Analysis. The correctness has been validated by using gray correlation analysis models. Results show that the standard set can reflect the chemical characteristics of aquifer accurately. It can be also used as a reasonable basis for discrimination of water irrush source in mine. |
