摘要
煤炭是我國(guó)的主要能源，隨著其工業(yè)生產(chǎn)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(lái)巨大壓力，也給當(dāng)?shù)厝藗兊娜粘Ｉ钤斐梢欢ǖ挠绊?。（可以介紹煤矸石的來(lái)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(huì)因地下水的淋溶作用溶出，并進(jìn)入地下水，對(duì)地下水水質(zhì)造成一定影響。本文通過(guò)模擬淋溶實(shí)驗(yàn)和浸泡實(shí)驗(yàn)分析得出：矸石林溶水中F-、Mn、和Cr6+ 超標(biāo)，PH值也稍偏高，浸泡實(shí)驗(yàn)中Zn在某個(gè)時(shí)間也會(huì)超標(biāo)，這些會(huì)造成地下水污染，其它各元素含量甚微，但隨時(shí)間的變化可能也會(huì)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
