| Abstract: | West mining area of Lizhu Iron Ore is damaged severely for tunnel deformation due to ground pressure activity, impacting the safe production of the mine.Through the on-site survey for appearance characteristics of ground pressure of mine, it analyzes the mechanism of the occurance of ground pressure and finds the main reasons.It puts forward for comprehensive treatment measures.After the implementation, it achieves good effect, and recovers the normal safe production of the mine. |
