摘　　要：为了解决东庞矿水淹巷道局部出现的围岩破碎、片帮冒顶的问题,结合现场具体地质条件,提出了采用锚杆、锚索+高分子化学注浆材料加固技术处理冒落区,通过改变巷道围岩结构提高岩体的整体强度。采取加固技术后,每班的施工进度由0.5 m提高到了1.5 m;采取加固技术比采用绕道法多回收煤炭资源5000 t。In order to solve the surrounding rock broken, sidewall spaIling and roof failing problems occurred in partial area of the mine water flooded roadway in Dongpang Mine, in combined with the site certain geological conditions, a combined reinforced technology with the bolt, anchor and polymer chemical grouting material was provided to treat the roof failing area. The integrated strength of the rock mass could be increased with the improved surrounding structure of the mine roadway. After the reinforced technology adopted, the reconstruction speed per shift was increased from 0.5 m to 1.5 m. In comparison with the roundabout way reconstruction method, the reinforced technology could recover more coal resources with 5000t.
