摘要
山西煤矿开采对水环境影响程度可划分为４类，即对水环境无影响区（Ⅰ）、影响轻微区（Ⅱ）、影响明显区（Ⅲ）及影响严重区（Ⅳ），其中Ⅰ，Ⅱ类区约占４６％，而水环境严重的矿山虽约占总矿山的５％，但年排水量却占６０％。以临汾、太原、忻州和阳泉的１００多个矿山最为严重，是综合治理的重点。
The degree of coal mining effect on hydrologic environment can be divided into: effectless region (Ⅰ ), lightly affected region (Ⅱ ), obviously affected region(Ⅲ ), and seriously affected region (Ⅳ ), of which Ⅰ and Ⅱ account for about 46%. However the mines, where hydrologic environment are seriously affeted by coal mining, amount to about 5 % of the total mines, their annual discharge of water is about 60% of the total. The hydrologic environment of more than one hundred mines in Lin fen, Taiyuan, Xinzhou and Yangquan are seriously affected, and the administration should focus on these areas.
