黄石地区露天矿山边坡分类及其生态修复应用

湖北省黄石地区矿产资源丰富,露天开采矿山众多,存在大量亟待生态修复治理的边坡。根据边坡的岩体岩性、岩体结构类型、坡度、坡向、坡高的组合关系,将黄石地区的露天矿山边坡划分为难治理型、较难治理型、较易治理型、易治理型四类,指出岩质、整体状和块状结构、陡坡及以上、顺层坡、高及超高边坡的生态修复难度较大。露天矿山边坡的类型及生态修复难易程度不同,应本着技术可行性、经济合理性、施工便利性原则,因地制宜地制订生态修复治理方案,以达到修复效果和经济性的协调统一。

Classification and Ecological Restoration Application of Open-pit Slope in Huangshi Area

Huangshi area of Hubei Province is rich in mineral resource and open-pit mines,there are a large number of slopes needing ecological restoration.According to the combination relationship of rock mass lithology,rock mass structure type,slope gradient,slope direction and slope height,the open-pit slopes in Huangshi area are divided into four types:difficult governance type,harder difficult governance type,easier governance type and easy governance type.It is pointed out that the ecological restoration of rock mass,overall shape and block structure,steep slope and above,bedding slope,high and super high slope is difficult.The types of open-pit mine slopes and the difficulty degree of ecological restoration are different.According to the principle of technical feasibility,economic rationality and construction convenience,the ecological restoration scheme should be formulated according to local conditions to achieve the coordination and unity of restoration effect and economy.
