摘要(Abstract)：

在瑞典,硫化物矿尾矿污染水的淋滤造成巨大的环境污染问题。本文概述一项利用天然土覆盖尾矿、最大限度地减少淋滤水的调查报告。研究表明,天然土渗水性是如此之高,以致于起不到明显的隔水效果。天然土盖层只能减少高降雨量期或迅速化雪期的渗水量,而且只对淋滤水峰值有作用。但是,作为一种蓄水体,位于尾矿顶部的密封盖层具有重要意义,它可以增加蒸腾损失。
Leachate of contaminated water from sulfide mine residual products is a great environmental problem in Sweden.This paper summarizes an investigation carried out in order to minimize the leachate production from the residual products by means of covering the deposits with natural soil materials.The study shows that natural soil types have such a high infiltration capacity, that no significant sealing effects are obtained.It is only possible to reduce the infiltration at periods with intense precipitation or rapid melting of snow, and then only the peaks in the leachate production are affected.Nevertheless, the sealing and covering layer on the top of a deposit are of great importance as water reservoirs and thus increasing the evapotranspiration losses.
