摘要
煤炭是我国的主要能源,随着其工业生产的不断发展,由采煤引起的地表塌陷给矿区生态环境带来巨大压力,也给当地人们的日常生活造成一定的影响。(可以介绍煤矸石的来源及其危害)利用煤矸石填充矿井不仅利用了煤矸石,减少了土地的占用量,而且又防止了地表塌陷。但是由于煤矸石中的有害元素会因地下水的淋溶作用溶出,并进入地下水,对地下水水质造成一定影响。本文通过模拟淋溶实验和浸泡实验分析得出:矸石林溶水中F-、Mn、和Cr6+ 超标,PH值也稍偏高,浸泡实验中Zn在某个时间也会超标,这些会造成地下水污染,其它各元素含量甚微,但随时间的变化可能也会溶出。

THE INFLUNCE OF FILLING SHAFT WITH GANGUES ON THE GROUNDWATER OF THE HE BI COAL COMPANY TEN MINE
Abstract
The coal is main energy of china .The surface collapse by mining bring about enormous pressure to ecological environment of mining area. And it created some influence to the people of mining area. Using gangues to filling shaft utilizes gangues and prevents the subsidence. But the hazards elements contained in gangues will infiltrate into groundwater through elevations by deep pit water. This paper has come to conclusions that through the simulative sprinkling and soaking experiment and analysis of the date the F-.Cr6+.and Mn in the water of eluviations and Zn in the water of soaked waster has exceeded standards and will pollute the groundwater ,but other heavy metal which may dissolve is very little and doesn’t bring any influence.
Keywords: gangues, filling, sprinkling experiment, soaking
