尾矿库是矿区的污染源,每当刮风季节,尾矿被风吹起,在下风向灰沙弥漫,严重地影响了居民的生活和植物的生长。在雨季,大量的地表径流冲刷,尾矿污染了水系。所以,对尾矿库进行复垦有着重要的意义。本文将介绍几个尾矿库的复垦实列。 实例一 向山硫铁矿第一尾矿库位于矿区东面,现已排放尾矿约250～300万米~3,占地面积约23万平方米,其中水田约5万多平方米。尾矿完全裸露着,每当刮风季节,处于下风向的居民和耕田受到“沙暴”的严重影响,所以向山矿于1980年底开始向尾矿库覆盖黄土。黄土层厚0.3米,覆盖面积为23万平
Tailings ponds are the source of pollution in the mining area. Whenever the windy season is over, the tailings are blown up by the wind and filled with lime-sand in the downspout, seriously affecting the lives of residents and the growth of plants. In the rainy season, a large number of surface runoff washed, tailings polluted the water system. Therefore, reclamation of tailings ponds is of great significance. This article will introduce several tailings reclamation real column. Example 1 The first tailings of pyrite mine is located to the east of the mining area. Tailings have been discharged from about 250 to 3 million m3, covering an area of about 230,000 square meters, of which about 50,000 square meters of paddy fields. Tailings are completely exposed. Whenever windy season, residents and farmland in the downwind direction are severely affected by “sandstorms”, the Xiangshan Mine began to cover the loess at the end of 1980. Loess layer thickness of 0.3 meters, covering an area of 230,000 square
