Abstract: In this paper, based on the analysis of the development status of the grouting materials, a comprehensive study on the performance of micro-fine cement-based grouting material I and II is conducted. Grouting with those kinds of cement has been used in very soft rock roadway at the Zhaozhuang Mine in Shanxi. It indicates that grouting reinforcement with the materials has made a good supporting effect and economic benefits. Maximum convergence of two sides is only 65 mm within six months. It is found that internal cracks have been filled and densified through georadar.
