我国煤田分布广,由于煤层赋存条件不同其含水情况也不同,一般北方煤田小,南方煤田大。水质也有差别,有的呈酸性,有的则因长时期补给与排泄条件不良,矿化度较高。但大量的基岩水是可供饮用的中性水。这些地下水在煤炭回采过程中,被大量排至地面,其中少数被开发利用,多数仍末引起各方面的重视。为了合理利用水资源,现对有关水处理方法简介如下:
The coalfield in our country is widely distributed. Due to the different conditions of occurrence of the coal seam, the waterconditions are also different. Generally, the northern coalfield is small and the southern coalfield is large. There are also differences in water quality, some acidic, while others due to poor supply and discharge conditions for a long time, higher salinity. However, a large amount of bedrock water is neutral water for drinking. These groundwater were largely discharged to the ground during the coal recovery process. A few of these groundwater were exploited and utilized, and most still did not attract the attention of all quarters. In order to make rational use of water resources, the relevant water treatment methods are as follows:
