为更好地改善和恢复朝国露天矿开采破坏的矿区生态环境，结合矿区的自然条件、开采技术条件和生态环境破坏预测，提出一种动态复垦模式。该动态复垦模式将矿区复垦工作动态地贯穿于采矿整个生命周期中，在采矿的设计、施工生产和闭坑不同阶段分别对采场、排土场、运输公路和工业场地进行复垦规划、动态复垦推进和剩余复垦，并在初期复垦结束后进行复垦效果评价与补充复垦。特别是在采场采剥期间，采用喷播绿化技术和覆土播种方法对采场台阶进行动态复垦，形成了边采矿边复垦的作业模式。针对目前矿区复垦存在的问题，进行了该动态复垦模式和采后复垦模式下的矿区复垦比较，结果表明该动态复垦模式可提前完成矿区复垦，且采场复垦效果好。建议矿区从现阶段开始依据该动态复垦模式进行复垦。%To better improve and restore the ecological environment damaged by mining of Chaoguo open pit mine,a dy-namic reclamation mode is proposed based on natural conditions,mining technique conditions and ecological damage prediction of the mining area. The dynamic reclamation mode makes the reclamation work dynamically throughout the entire process of mining project. Reclamation planning,dynamic reclamation advance and comprehensive reclamation work of stope,dump,trans-port roads and industrial site are respectively carried out at different stages of design,construction and production and closure of mining. Reclamation effect evaluation and supplementary reclamation will be made after the end of initial stage of reclamation. Especially during the stripping and mining in stope,spray seeding technique and the soil covering planting method are applied for dynamic reclamation of stope steps, making the stope reclamation and mining work synchronously. Aimed at the existing problems in the reclamation of mine area,the dynamic reclamation mode and the mining afterwards reclamation mode are sepa-rately used and compared in the area reclamation. The results show that the former can complete the reclamation earlier with better effect,so it′s suggested that the mining area be restored by taking the dynamic reclamation mode from now on.
