摘　　要：为确保3308综放工作面末采期间围岩稳定,借助数值模拟、理论分析的方法确定停采煤柱合理宽度,最终设计停采线煤柱宽度不小于49 m。为降低工人劳动强度,利用金属网配合柔性网护顶的方法,实现了工作面安全快速回撤,提高了护顶效果,降低了劳动强度,缩短了末采周期,节约了支护成本,对类似条件综放工作面的高效回撤提供了有效借鉴。In order to ensure the stability of the surrounding rock during the final mining of 3308 fully-mechanized caving face,the reasonable size of the stop mining coal pillar was determined with the help of numerical simulation and theoretical analysis,and the final design of the width of the stopping line coal pillars needs to be more than 49 m.In order to reduce the labor intensity of workers,the method of metal mesh combined with flexible mesh to protect the roof of the working face was used to realize safe and rapid withdrawal of the working face,improve the effect of roof protection,reduce the labor intensity,shorten the final mining period and save the support cost,which can provide an effective reference for the efficient withdrawal of the full-mechanized caving working face under similar conditions.
