黄河中游神木、府谷、东胜地区,蕴藏着丰富的煤炭资源。随着这里煤炭资源的大规模开发,新增水土流失就成为一个突出的环境问题。因此,正确评估矿区新增水土流失量,对于积极有效地控制水土流失,加强监督管理,具有重要意义。 一、矿区开发新增水土流失的特点 根据地表形态破坏的不同,神府东胜矿区的水土流失可分为四类,即:露天矿区的水土流失,铁路、公路工程的水土流失,井矿区的水土流失,生活区及工业场地的水土流失。 露天矿区水土流失的特点是地表形态破坏严重,地表覆盖层剥离量大,弃土弃石集中,如处理不当则易形
The middle reaches of the Yellow River Shenmu, Fugu, Dongsheng area, rich in coal resources. With the large-scale development of coal resources here, new soil and water loss has become a prominent environmental issue. Therefore, a correct assessment of the amount of newly added soil and water loss in the mining area is of great significance for the active and effective control of soil and water loss and enhancement of supervision and management. I. Characteristics of Newly-added Soil and Water Loss in Mining Development According to the different damage of surface morphology, soil erosion in Shenfu Dongsheng mining area can be divided into four categories, namely, soil and water loss in opencast mining areas, soil and water loss in railway and highway projects, Soil and water loss, soil erosion in living areas and industrial sites. The characteristics of soil and water loss in surface mine are serious damage to the surface morphology, large amount of peel off of the surface covering layer, concentration of spoil and spoil, improper handling
