摘要
煤矿开采后,地下水充填采空区形成"老窑水",并通过各种途径污染相邻地区的地表水和地下水。为了探讨"老窑水"的治理方法,选取水中添加煤+石灰、煤+石灰岩、煤3种情况的浸泡水样,开展了为期270d的室内对比性分析试验。结果表明:煤+石灰+水样品处理效果较好。研究结果对煤矿矿井闭坑前开展"老窑水"的处理具有一定的参考价值。
After excavation of a coal mine, groundwater will fill in the mined - out area to form the ＂old kiln water＂ which will pollute the neighboring area through various ways. In order to study the treatment method for ＂ old kiln water＂ , 3 kinds of water samples, namely, water ＋ coal ＋ lime, water ＋ coal ＋ limestone, water ＋ coal, are used to carry out a 270 - day indoor soaking experiment. The experiment results show that the treatment for mine water of old kilns by the sample of water ＋ coal ＋ lime is effective. The experiment result has a certain reference value for the treatment of ＂old kiln water＂ before the coal mine is closed.
