摘　　要："综放复采"收尾及回撤阶段,尤其是回撤通道的形成,其主要难点在于顶板条件的特殊性,处于小煤矿开采大范围空棚空巷和断层带区域形成大跨度回撤空间,必须优先考虑顶板的可靠支护和控制。红会一矿在1609综放工作面收尾回撤中,采用常规支护和特殊支护结合的技术,有效控制了空棚空巷区域的顶板压力,形成了较为安全的回撤作业空间。In the stage of fully-mechanized top coal caving mining ending and retracement, especially in the formation process of retrace- ment channels,the main difficulty is special roof conditions, large retracement space was formed in the gob area, regions without shed and fault zones,so it must consider reasonable supporting and control of roof in advance. In the process of ending and retracement on 1609 fully-mechanized caving face in Honghui No. 1 Coal Mine,combined technology of conventional supporting and special supporting was used into practice. With the application of this technology, roof pressure was effectively controlled in gob area and regions without shed,and a relatively safe retracement space was formed.
