一、工矿区水土流失的危害(一)侵占、破坏土地资源。工矿企业在生产过程中排放出大量的固体废弃物,使越来越多的土地资源被侵占或受到严重破坏。例如:平朔煤矿是我省年产最高的一座现代化露天煤矿,日产原煤5万吨,年产1,500多万吨。矿山基建剥离土量5,700~6,000万立方米,破坏土地资源面积18.85平方公里,采剥比为1:4~10(一般为1:5~6)。
First, the hazards of soil and water loss in industrial and mining areas (A) encroachment, destruction of land resources. Factories and mines discharge large amounts of solid waste in the production process, causing more and more land resources to be invaded or severely damaged. For example: Pingshuo mine is the highest annual output of a modern open pit mine, Nissan 50,000 tons of coal, with an annual output of more than 15 million tons. Mine infrastructure stripping soil volume 5,700 ~ 6,000 cubic meters, the destruction of land resources area of 18.85 square kilometers, mining stripping ratio of 1: 4 ~ 10 (usually 1: 5 ~ 6).
