摘要
煤炭是我國的主要能源，隨著其工業(yè)生產的不斷發(fā)展，由采煤引起的地表塌陷給礦區(qū)生態(tài)環(huán)境帶來巨大壓力，也給當?shù)厝藗兊娜粘Ｉ钤斐梢欢ǖ挠绊憽＃梢越榻B煤矸石的來源及其危害）利用煤矸石填充礦井不僅利用了煤矸石，減少了土地的占用量，而且又防止了地表塌陷。但是由于煤矸石中的有害元素會因地下水的淋溶作用溶出，并進入地下水，對地下水水質造成一定影響。本文通過模擬淋溶實驗和浸泡實驗分析得出：矸石林溶水中F-、Mn、和Cr6+ 超標，PH值也稍偏高，浸泡實驗中Zn在某個時間也會超標，這些會造成地下水污染，其它各元素含量甚微，但隨時間的變化可能也會溶出。

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
