摘　　要：针对永煤集团陈四楼煤矿2209综采工作面出现的冒顶事故,采用化学注浆加固技术对工作面冒落区及煤壁进行了注浆加固。现场施工表明:充填材料威尔浮和加固材料波雷因能满足煤矿易冒区冒顶事故的防治要求。2209综采工作面安全推进至终采线,创造了较好的经济效益和社会效益,具有推广价值。Aimming at the roof falling accident in 2209 fully mechanized working face of Chensilou Coal Mine of Yongcheng Coal Industry Group,the authors have chosen the technology of injecting chemical reinforcing grout to strength the roof and ambient coal body. Practice has indicated that Weirfu used as filling material and Poleiyin used as reinforcing material can fit the need of prevention of roof falling in easily caving section. The 2209 fully mechanized working face has been mined to the terminal line safely, and much economic performance and social benefit has been created, this technology has the value to be popularized.
