【摘要】 本文基于矿井水化学测试数据，通过系统聚类分析与贝叶斯判别法，开展陈四楼煤矿矿井充水水源水化学成因机制研究，明确了矿井水化学来源及构成，查明了矿井主要充水水源的水化学成因，结果发现，各含水层间水化学特征差异显著。基于变异系数热点图分析，结果表明K⁺+Na⁺、Ca²⁺、Mg²⁺、HCO₃^-存在较大的变异系数，属于水化学作用积极因子。相关性分析表明，井田灰岩水与砂岩水成分存在显著差异，而与地表水样具有一定的同源性。采空水中元素相关性类型组合与砂岩裂隙水、灰岩裂隙水同时存在一定的相似性和差异性，这与其来源是一致的。系统聚类法结果表明，陈四楼煤矿含水层总体独立性强，仅局部存在两相邻含水层相近现象。从陈四楼井田地下水Gibbs图来看，陈四楼井田周边地表水、灰岩水和砂岩水主要位于水迟缓交替作用区域，地下水成分主要受蒸发浓缩作用控制，其中灰岩水和砂岩水蒸发浓缩作用影响差异不大，而地表水的蒸发浓缩作用程度在时空上存在差异性。更多还原

【Abstract】 Based on the hydrochemical test data of mine water, this paper studied the hydrochemical genetic mechanism of mine water source in Chensilou Coal Mine by systematic cluster analysis and Bayesian discriminant method, clarified the hydrochemistry source and composition of mine water, and found out the hydrochemistry causes of the main water source of the mine. The results showed that the hydrochemistry characteristics of each aquifer were significantly different. Based on the analysis of the variation coefficient hotspot map, the results showed that K++Na+, Ca²⁺, Mg²⁺and HCO₃^-had a large variation coefficient, which was a positive factor of hydrochemistry process. The correlation analysis showed that there were significant differences in the composition of limestone water and sandstone water in the mine field, and they had certain homology with surface water samples. The correlation type combination of elements in goaf water had certain similarity and difference with sandstone fissure water and limestone fissure water, which was consistent with its source. The results of the systematic cluster method showed that the overall independence of the aquifer in Chensilou Coal Mine was strong, and only two adjacent aquifers were similar in local area. According to the Gibbs diagram of groundwater in Chensilou mine field, the surface water, limestone water and sandstone water around Chensilou mine field were mainly located in the area of water slow alternation action. The composition of groundwater was mainly controlled by evaporation and concentration, among which the effect of evaporation and concentration of limestone water and sandstone water was not much different, while the degree of evaporation and concentration of surface water was different in time and space.更多还原
