充填接顶是充填采矿法的重要环节，也是充填作业的技术难点。以大冶铁矿东采区由崩落采矿法转为分段空场嗣后胶结充填采矿法所面临的充填接顶技术问题为工程背景，分析了在现场充填中可能影响充填接顶的相关因素，进而有针对性地提出了一系列解决充填接顶问题的技术措施，为指导和改善大冶铁矿充填采场的充填接顶问题提供理论依据及技术支持。
Roof-contacted filling is not only an important part of stoping and filling ,but also a technical difficulty of filling operation .Based on the engineering background of east mining area of Daye iron mine and the problems the mine faces after the transition from sublevel caving to sublevel open stoping and subsequent cemented filling .The pa-per analyzes related factors that may affect roof-contacted filling on site , and then puts forward a series of technical measures to solve the problem of roof-contacted filling effectively .It has provided the theoretical basis and technical support to guide and improve the roof-contacted filling issues of Daye iron mine .
