摘　　要：根据工作面煤体上方直接顶及老顶悬露面积的不同,建立不同的围岩结构模型,采用理论分析的方法,得出了长壁综放回采对工作面顺槽的影响机理,并以余吾煤业公司S2205综放工作面为工程背景,对综放回采影响下工作面顺槽变形规律进行实测分析,得出了该地质条件下综放回采对工作面顺槽的影响范围及程度。Upper immediate roof area is different from the suspending area of main roof over the working face, so different surrounding structure models should be built. By the theoretical analysis, the influential mechanism of long-wall fully mechanized caving on the crossheading is concluded. According to the S2205 working face, Yuwu Coal Industry Co., the deformation rule of crossheading is studied and the influential scope and degree under the local geological condition are obtained.
