Experiment and Calculation of Vibration in the Roof Caving of Underground Mine Cavity

Abstract

Abstract: The shock wave produced by the roof caving against the bottom in underground mine cavity will have impact on the nearby structures and facilities. In view of such problem that may occur in some large underground mine cavities that haven't been treated for a long time, a simulation experiment was made. From the analysis of the experiment data calculation, the propagating law of cavingcaused vibration was drawn, providing a theoretical reference to the evaluation of vibration impact.

Key words: Cavity, Caving caused vibration, Simulation experiment, Calculation and analysis
