摘　　要：为分析卧龙湖8101工作面涌水补给源以及集水形式,统计整理了本矿井地下水样品常规水质分析数据62组。利用多元统计组合模型与maltab方法相结合对8101工作面涌水水源进行分析研究.结果说明:8101工作涌水水源与本矿10煤砂岩水质类型一致。卧龙湖矿各地层地下水水质的首要因子为Ca2+,Mg2+,SO42-,体现太灰水的外来补给;第二因子是阳离子交替吸附作用,其涌水体现了地下水静储量消耗。多元统计模型与maltab方法相结合是一种稳定性高且切实有效,适用于地下水水源水化学分析的方法。For the analysis of Wolong Lake 8101 working face water inrush source and water collection, statistics of the mine groundwater samples of conventional water quality analysis data of 62 groups were collected. Using a combination of models and multivariate statistical methods combining maltab, this paper illustrated the gushing water of 8101 Face. The results show that the water resource of 8101 consistent with the mine 10 coal sandstone type. The primary factor of Lake Wolong ore stra- tum of groundwater quality is Ca^2＋. Mg^2＋ ,SO4^2- , which reflects Taiyuan limestone water supply being from the other water resource; the second factor is the cation exchange adsorption, which embodies the static storage consumption of groundwater flow. The method of multivariate statistical model and maltab is a kind of high stability and effective, which is applicable to discriminate the groundwa- ter source water chemistry.
