摘　　要：综放工作面由于设备多、设备型号大,末采期间工作面顶板管理较综采工作面复杂,对于采空区下综放工作面,在回撤期间对顶板要求更高,国内外没有可以借鉴的经验。内蒙古福城矿业有限公司1502N为近距离采空区下放顶煤工作面,通过对工作面停采位置、层位、工作面顶板支护方案等方面进行全面论证,保证工作面末采及回撤期间的顶板安全。The roof management of fully mechanized caving face is more complicated than that of fully mechanized caving face at the end of mining due to the large number of equipment and large type of equipment.For fully mechanized caving face under goaf,the roof requirements are higher during the pullback period.There is no experience for reference at home and abroad.Inner Mongolia Fucheng Mining Co.,Ltd.,1502N is the top coal face lowered in close goaf area.Through comprehensive demonstration of stop-mining position,horizon and roof support scheme of the working face,the roof safety during the final mining and pullback of the pullback face can be ensured.
