摘要:
海底矿山突水是矿山开采亟待解决的问题,通过对矿山巷道水的研究,能够划分出矿山突水水源类型,进而对突水可能性作出预测。以山东三山岛金矿西山矿区地下水系统为例,对其31个水样的水化学资料进行多元统计分析研究。利用因子分析法对存在相关关系的变量进行空间降维处理,找出能够反映大于90%水样水化学信息的公共正交因子,以其作为系统聚类变量。运用系统聚类并结合实际地下水性质,将研究区地下水划分为典型的2类,然后建立矿区水源的Bayes线性模型,并对其进行验证。通过因子分析法和系统聚类分析法得出,-375 m中段涌水水源划分为2种类型,并得出2种具体的判别函数。结果表明:多元统计方法判别水源具有快速、准确且经济的特点。
