| 摘 要： | 淋溶是有害微量元素从煤或煤矸石中析出后污染环境的重要途径。本文在对河南新密—荥巩矿区煤矸石淋溶实验的基础上,研究了有害微量元素从煤矸石中淋溶析出的浓度及淋溶过程中pH值的变化规律,探讨了不同淋溶实验方法对有害微量元素溶出的影响,并对有害微量元素溶出的环境意义进行了讨论。

| Abstract: | Leaching is one of important ways of hazardous trace elements from coal-waste rock and ash causing environment pollution.In this paper,based on the leaching experiments of coal-waste rock from Xinmi-Xinggong mining field in Henan Province.The changing regularities of pH values and leaching contents of hazardous trace elements from coal-waste rocks are studied.The different methods of leaching experiments impact on the leaching out of and the environmental significance of hazardous trace elements from coal-waste rocks are analyzed. |

| Keywords: | hazardous trace elements leaching coal-waste rock environmental significance |
