矿山土地复垦模式探讨

通过对西北地区20多处典型矿山地质环境治理成效调研,回顾了我国矿山土地复垦发展历程,系统地对我国现阶段矿山露天采场、固体废弃物堆积、地面塌陷对土地的危害进行了分析。研究了露天采场采坑及边坡土地复垦模式,固体废弃物中废石堆和煤矸石堆复垦、处理和资源化利用复垦模式,地面塌陷区和塌陷积水区土地复垦模式,这些土地恢复治理实践经验的总结对指导矿山土地复垦的实践具有一定的借鉴意义。

Discussion for Mining Land Reclamation Models

For the sake of interchanging some ideas about mining land reclamation and promoting the research level of mining land reclamation models in China, the writer investigated the treatment effect of more than 20 typical mining geology environments in the northwest region in 2010, looked back mining land reclamation development process in China, and systematically analyzed the harm of the open pit, solid waste stack-yard or grounds collapse to land. On this basis, the writer had an exploratory research on the land reclamation models of the open pit, the solid waste stack-yard and coal gangue treatment or reusing, the grounds collapse to land deformation area or water-logged ground. All of the models were some practical experience summary, and had some stronger applicability or operability, and had considerable significance to the mining land reclamation work.
