孙疃矿突水水源化学特征及判别模型

Chemical Characteristics and Discriminant Model for Water Bursting Source in Suntuan Coal Mine

摘要: 为了实现对矿井突水进行准确快速地水源类型判别，分析孙疃矿主要含水层的水化学特征，以Na⁺+K ⁺、Ca²⁺、Mg²⁺、Cl^-、SO^2-₄、HCO^-₃实测含量为依据，借助SPSS统计软件对主要含水层水样进行逐步判别分析。在此基础之上，筛选出Ca²⁺、Cl^-、SO^2-₄、HCO^-₃ 4个指标作为参考变量建立起适用于孙疃矿的突水水源判别模型。经过验证，结果表明该模型表现出较好的判别效果。

Abstract: In order to realize accurate and quick discrimination of mine water bursting source type, we analyze the water chemical characteristics of main aquifers in Suntuan Coalmine and use SPSS to study the water samples of main aquifers by the stepwise analysis based on the test results of Na⁺+K⁺, Ca²⁺, Mg²⁺, Cl^-, SO^2-₄, HCO^-₃. On the basis, Ca²⁺, Cl^-, SO^2-₄, HCO^-₃ are chosen to establish discriminant model suited to Suntuan Coalmine water bursting source. After verification, the result shows the model has better effect on discrimination.
