ABSTRACT

Geomorphic-based mine restoration of clay quarries in Tortosa (Catalonia) was co-funded by the European Union’s LIFE programme. The landform design was made with GeoFluv-Natural Regrade. Their building was performed with existing machinery pool and operators. The main constraint was the impossibility of setback regrading of pre-existing-benched highwalls. Progressive geomorphic mine restoration neither reduced mineral production nor changed the operations. The approach has resulted in higher landscape functionality and integration. Monitoring showed localised erosion due to poorly planned discharge of road runoff and sporadic tunnel erosion. Sediment movement at the designed drainage network is similar to the local fluvial dynamics.

摘要

托尔托萨（加泰罗尼亚）粘土采石场基于地貌的矿山修复由欧盟的 LIFE 计划共同资助。地形设计是用 GeoFluv-Natural Regrade 制作的。他们的建筑是使用现有的机械池和操作员进行的。主要限制因素是不可能对预先存在的长凳式高墙进行后退重新分级。渐进式地貌矿山修复既没有减少矿产产量，也没有改变运营方式。这种方法导致了更高的景观功能和集成。监测表明，由于道路径流排放和零星隧道侵蚀计划不当，造成局部侵蚀。设计排水管网的沉积物运动类似于当地的河流动力学。
