铁矿生产由于开挖矿床、排弃废岩,必然要扰动、压埋原始地表,破坏原有水土保持设施。以本溪宏发铁矿工程为例,分析矿区开采的特点和水土流失成因,抓住重点部位和关键环节因地制宜,因害设防。同时,着重讨论了如何减少矿区新增占地和斜坡的植被防护,以期对类似工程的水土保持提供指导。
Iron ore production as a result of excavation of deposits, abandoned waste rock, will inevitably disturb, buried the original surface, destroy the original soil and water conservation facilities. Taking Benxi Hongfa iron ore project as an example, this paper analyzes the characteristics of mining and the causes of water and soil loss, and grasps the key parts and the key links according to local conditions and fortifies the fortifications. At the same time, it focuses on how to reduce the vegetation cover of newly-added lands and slopes in the mining area so as to provide guidance for the soil and water conservation of similar projects.
