Abstract: In order to further improve the filling efficiency and ensure the filling quality, a real-time compaction monitoring technology was used to study an evaluation method of vermiculite solid filling effect based on vibration behavior analysis. Based on the actual operation of the on-site filling process to compact the distance from the top of the mechanism, and based on the theory of vibration compaction, the mathematical relationship between the acceleration and the filling effect of the compaction mechanism is discussed, and a basis for the evaluation of the filling effect of the acceleration and the filling rate; By analyzing the compaction mechanism of the filling material, using the Compaction Value (CV) as the indicator of the compaction state of the filling material, the in-depth analysis of the acceleration waveform and vibration intensity of the compaction mechanism on the filling effect The rapid evaluation model for the filling effect of vermiculite material was established. The test results show that there is a strong correlation between the CV and the compaction of the filling body, and the regression model of the compacted degree has higher accuracy. This method can realize rapid evaluation of the filling effect, effectively improve the filling quality, and provide a new way to improve the filling mining efficiency.
