【摘要】 当前矿山开发对地下水环境的变化已经产生了影响,尤其是对矿区地下水水质的影响较大。新汶矿区有半个多世纪的煤炭开采历史,但对其地下水水质特征和评价较系统地研究尚属首次。论文结合新汶矿区水害治理重大课题和山东省中青年科学家奖励基金课题,广泛地收集了新汶矿区水质分析资料,利用Visual FoxPro建立了新汶矿区水质资料管理系统。研究了矿区地下水主要含水层的水化学成分特征及其变化规律,总结了研究区Na+、K+、Ca2+、Mg2+、HCO3-、SO42-、Cl-的水化学分布特征,分析了奥灰、徐灰和四灰的SO42-、Ca2+的变化规律。利用最小二乘法原理,建立了水质变化趋势预测模型,对硫酸盐浓度的变化趋势进行了回归分析。应用模糊数学原理,建立了模糊综合评价模型,并结合国家水质质量标准,通过对108个水样综合评价,划分了研究区水质级别,评价了研究区的地下水污染程度,得出了研究区地下水水质较差和硫酸盐为主要污染物的结论。应用GMS(Groundwater Model System)软件,模拟了研究区地下水渗流场和溶质运移特征,得出了不同时段的地下水渗流场和SO42-的时空变化特征。

【Abstract】 The exploitation of mining affects of groundwater environment, especially to quality of mining groundwater. XinWen coalfield has half a century exploitation history, but it is the first time that the study on its groundwater quality character and evaluation. Based on the summarized of data in internal and foreign country, analyze geology and hydrologic geology of XinWen mining. This paper is combined with magnitude task of Xinwen coalfield and Rewards funds of Youth Science in ShanDong. The author reorganized and analyzed the hydrogeology data, established the XinWen Mine hydrology of analyzing database management system by use of Visual FoxPro software, realized the criterion management, provide a utility software for managed ,inquire and use of data on the scene of action. In this paper, the author studied chemistry component character and diversification rule of mine aquifers in mine, summarized chemistry distributing character of Na+, K+, Ca2+, Mg2+, HCO3-, SO42-and Cl- in coalfield, and analyzed diversification rule of SO42-, Ca2+ that in Ordovician-limestone、 Xujiazhuang-limestone and fouth limestone aquifers. Using the least square method bring forward the formula of movement current that quality of groundwater, and predicate the diversification current of sulfate. With theory of fuzzy mathematics, established the model of vague colligate estimate. Combined with the model with criterion of country, divide the quality of mining groundwater into several levels by evaluating 108 water samples. And evaluated contaminated grade, educed the conclusion that water quality is relatively poor and the mine contaminant are sulfate. And using the software of Groundwater Modeling System, the author simulated the feature of groundwater’s flow field and solute travel.
