Application of Chemical Grouting Material in the Controlling Process of Argillaceous Roadway under Rich Water Condition
Weakening phenomenon of argillaceous surrounding rock under water effect universal exists in the excavation and supporting process of roadway in coal mine, the destructive effect of water acting on the argillaceous surrounding rock serious threatens the coal mine safety production. In this paper, the application of chemical grouting material in the control process of argillaceous roadway under rich water condition was studied. Simultaneously the sealing and strengthening mechanism of chemical grouting and its advantages were also analyzed. A filed application of the technique was aslo conducted and the observation results in-situ identify that chemical grouting combined with high-performance supporting technology can effectively maintain the long-term stability of argillaceous roadway under rich water condition.
