摘　　要：以阶段嗣后充填采矿法的司家营铁矿南区为研究背景,在现有的工程地质资料的基础上,运用经典理论模型法和工程类比计算法,通过对矿房、胶结充填体、围岩作用下充填体和采场承载结构矿柱等四个方面进行稳定性分析,以及对充填体强度与采场围岩进行匹配研究,进而验证充填体强度在回采和充填过程中能否满足稳定性的要求。Abstracts The research background in this paper is the south region of Sijiaying Iron Mine using sublevel open stoping with subsequent filling method. Based on the existing engineering geological data, using the method of clas- sical theoretical model and engineering analogy, the stability is analyzed in four aspects： room, cementing filling body, filling body under the action of surrounding rock and stope pillar bearing structure. Matching study on the strength of filling body for stope wall rock is presented as well in this paper, and whether the strength of filling body can meet the requirements for stability in stoping and filling process is verified.
