摘　　要：北洺河铁矿为践行“绿水青山就是金山银山”的绿色发展理念,探索利用选厂尾矿治理地表塌陷区方案。通过对北洺河铁矿塌陷区稳定性分析以及对全尾砂膏体制备、输送、胶结充填技术可行性试验研究,并结合经济估算、环境和社会效益等综合分析,认为全尾砂胶结充填治理塌陷区的方案可行。In order to act on the concept of green development that lucid waters and lush mountains are invaluable assets,Beiminghe Iron Mine actively explores the schemes for the management of areas with surface subsidence by using tailings.The stability analysis of the land subsidence in the iron mine,the experimental study for the technical feasibility of preparation and transportation of total tailings paste,as well as feasibility of employment of cemented backfill technique were all conducted.Based on the comprehensive analysis in terms of economic estimation,environmental and social benefits,it is concluded that this cemented total tailings backfill technique is suitable for treating land subsidence.
