Abstract
This text takes the fall to pieces round rock of Wuyang Coal Mine 76 Roadway maintenance technique as an example, from improving the structure and the strengthen of surrounding rock. Under the condition of original support, it put forward the project of application bolt and grouting reinforcement in 76roadway. It expatiates on the structure, specification and construction technology of the birdcage counter bolt and analyses the concentration of concrete grouting and the effect of grouting pressure to diffusion limits with the numerical simulation software UDEC. It tkes greatly good practice effect with current test and application.关键词
