矿井非常规水资源开发利用对改善水生态环境和节约保护水资源具有重要的现实意义。以肥城盆地矿区为研究对象，首先，采用Mann-kendall和Spearman识别了1982年－2011年矿井涌水量时序变化特征，同时对影响矿井涌水的关联因素进行相关性分析，结果显示矿井涌水量呈现增长趋势，矿井涌水量主要受盆地水文地质条件影响，同时与煤炭开采量、降雨也存在一定相关性；其次，采用国际通用水化学分析软件AquaChem5.1识别矿井水化学特征与类型，结果显示矿井水硬度与硫酸盐含量较高，属于高矿化度、酸性矿井水；最后，在以上分析基础上，建立矿井水合理开发利用模式，可为肥城地下水环境保护和水资源可持续利用提供借鉴。

Development and utilization of the unconventional water resources in the mine have important practical significance in improving ecological environment and saving water resources. In this paper, both Mann-Kendall and Spearman methods were applied to identify the variation characteristics of mining water inflow from 1982 to 2011 in the Feicheng Basin mining area, and the impact factors affecting mining gushing water were analyzed. The results showed that mining water inflow has a significant increasing trend, which is mainly affected by the hydrogeological conditions in the basin and is also correlated with coal mining yield and rainfall. The international water chemical analysis software, AquaChem5.1 was adopted to identify the characteristics of mining water quality, and the results showed that mining water has high hardness and sulfate content, which suggested that it is high-salinity and acid water. Based on the above analysis, the reasonable development and utilization mode of mining water was established to provide technical support for groundwater environment protection and sustainable utilization of water resources in the Feicheng Basin.
