| Abstract: | Large mining height working face of sihe mine encountered areas of special geological in mining as the background. Grouting reinforcement mechanism of coal and rock was intruduced, the application of cement slurry and chemical grouting technology were analyzed, the advantages and disadvantages of two grouting materials were analyzed too. The practice proved that grouting reinforcement technology of surrounding rock can effectively improved the special geological area of the coal and rock strength, the safety of working face ensured too. |
