摘　　要：我国富水第四系覆盖铁矿资源丰富。此类矿床上部覆盖的第四系变质岩层中含有多层砂砾含水层,地表为良田和村庄,不允许塌陷,安全采矿的技术关键是保护第四系不受破坏。对该类型某大型铁矿开展了采矿方法、隔离矿柱及采场结构参数、充填材料、系统与工艺等技术研究,成功解决了矿山安全采矿技术难题,并应用于生产,获得了好的经济效益和社会效益。China's water - rich Quaternary is rich in iron ore resources.The upper multi - layer in Quaternary of such deposits is metamorphic aquifer rocks.The surface is covered by the farmland and villages,which are not allowed to collapse. The key technology for safe mining is to protect against destruction of the Quaternary.The mining methods,isolated pillar,stope structure parameters,filling materials,systems and process technologies for this kind of mines are researched, successfully solving technical problems in mining,mine safety and being applied into production.Then good economic and social benefits are achieved.
