摘要/Abstract

摘要： 由于生产方面要求，下告铁矿采矿方法需从原来的空场法变更为无底柱分段崩落法。但矿山前期空场法开采形成了较多的采空区，在采矿方法的变更中涉及到遗留资源的集约整合利用和空区放顶技术。对现有空区进行了稳定性分析后，确定了遗留资源的集约利用和最终的空区放顶方案，对类似矿山的残留资源回收和空区放顶研究具有一定的参考意义。

关键词: 空场转崩落, 资源整合, 空区放顶

Abstract: Xiagao iron ore will transfer its mining method from open stope into pillarless sublevel caving method due to the production needs. But there appear many goafs under resulting from the original open stope method. The resources intensive integration and goafs roof caving technology are concerned during the transferring. In the research，the stabilities of current goafs are analyzed to identify the scheme of roof caving and intensive integration of remained resources. The research provides a certain reference for the intensive integration of remained resources and the roof caving of similar mines.

Key words: Transferring from open stope into caving, Integration of resources, Roof caving of goaf
