The invention provides a method for soilless tailing reclamation. The method comprises the steps of tailing concentration, subsidence area, gully and swale filling, soilless tailing matrix preparation, soilless tailing matrix coverage and the like. A large number of tailings can be treated, tailing occupation is reduced, environment harm is reduced, meanwhile, tailing resources are reasonably utilized, and the resource utilization rate is increased. Good economic benefits and social benefits are achieved. The obtained soilless tailing matrix is high in organic matter content and good in water retaining property and gas permeability, can improve the soil physicochemical property, provides nutrients needed by plants and has the good repairing effect on mining rehabilitation. 本发明提供了种无土尾矿复垦的方法，包括尾矿浓缩，充填塌陷区、冲沟、低洼地，制备无土尾矿基质和无土尾矿基质覆盖等步骤，不仅可以处理大量尾矿，减少尾矿占地，减少环境危害，同时使尾矿资源得到合理利用，提高资源利用率。具有较好的经济效益和社会效益。所制得的无土尾矿基质机质含量高，保水性和透气性好，可改善土壤的理化性质，提供植物所需营养，对矿山修复具有较好的修复效应。
