Exploration on the Supporting Technology of Fractured Surrounding Rock and Dynamic Pressure Roadway

Through the support reinforcement practice at the eighth mining area-110 m crossdrift and at the fifth mining area-105 m crossdrift in Su'er coal mines of Fujian coal power company,the support pattern under the influence of roadway mining was studied when mine transferred to deep mining,and the geological conditions became complicated and geopressure increased obviously,which provided a reliable basis for support reform of this kind of roadways.
