【摘要】 本文在对许厂煤矿地质及水文地质背景条件调查及研究的基础上,以对开采下组煤有主要影响的矿井主要突水含水层（太原组第十_下层石灰岩岩溶、裂隙承压含水层、太原组第十三层石灰岩岩溶、裂隙承压含水层和奥陶系石灰岩岩溶、裂隙承压含水层）为研究对象,以Ca²⁺、Mg²⁺、K⁺ + Na⁺、Cl^-、SO₄^2-、CO₃^2-、HCO₃^-、pH值、TDS为重点分析基础,主要研究了突水含水层常规水化学特征及水文地球化学特征;揭示了奥灰、十_下灰和十三灰三个主要突水含水层的地下水的迳流条件及水力联系状况;并将饱和指数模型引入到矿区地下水水化学场特性的研究当中,得出了矿区奥灰、十_下灰与十三灰三个含水层主要矿物的饱和指数,分析了三个含水层在各水文单元的迳流特性。通过对主要突水含水层水质的动态分析测试,得出了各含水层在不同水文单元的水力联系情况。研究结果表明根据突水含水层的水文地球化学特征可以准确判断含水层的补给、径流和排泄关系以及各含水层之间的水力联系状况。在此基础上,运用模糊识别模式建立了突水含水层水源判别模式。在模糊识别法对水源判别的研究中,判别准确率达到89.47%,所以可以用模糊识别模型对矿井突水水源进行判别。本文的研究成果对矿区突水水源判别和防治水工作具有一定的使用价值及和参考意义。更多还原

【Abstract】 Basing on the mastery for the background of geology and hydrogeology about Xuchang coal mine sufficiently,and regarding main water-bursting aquifer（the Ordovician limestone aquifer,the Taiyuan 10th floor karst limestone aquifer and the Taiyuan 13rd floor karst limestone aquifer） as the researching object,on the basis of Ca²⁺,Mg²⁺,K⁺ + Na⁺,Cl^-,SO₄^2-,CO₃^2-,HCO₃^-, pH value and TDS,the hydro-geochemistry characters of routine hydro-chemistry and environment isotope were investigated.Saturation index model was introduced to the stady of mine groundwater chemical characteristics.Reached the saturation index of mineral in the Ordovician limestone aquifer,the Taiyuan 10th floor karst limestone aquifer and the Taiyuan 13rd floor karst limestone aquifer,and analysis hydraulic connections characteristics of the three aquifers.Though the dynamic water analysis in the main pouring water aquifer,reached the hydraulic connections in different modules of the three aquifers.The results show that pouring water aquifer hydro-geochemical characteristics can accurately judge the aquifer recharge,runoff,excretion,and hydraulic connections characteristics.According to the above,by applying methods of fuzzy recognition model,the water bursting aquifer differentiation models of the water sources were created.The research production of this paper is valuable and significant for the differentiation of water-bursting sources and the work of water prevention and cure in the coal mine.更多还原
