Study on Three-Dimensional Dynamic Stability of Open-Pit High Slope under Blasting Vibration

Abstract The propagation process of blasting vibration has always been a difficult problem affecting the stability high slopes in open-pit mines. Taking Jianshan Phosphorus Mine as research background, combined with engineering geological investigation, field test, monitoring, numerical simulation technology, and theoretical analysis, three-dimensional dynamic adjacent slope after was systematically studied. In our study, small-diameter buffer shock-absorbing technology near proposed, which greatly improved production efficiency. Through regression analysis large amount test data, law stope Haifeng obtained. addition, by establishing four geomechanical models, slope’s own frequency, damping characteristics, response acceleration distribution detonation were studied, respectively. On other hand, under action Ei Centro wave 8-degree seismic intensity, maximum total displacement calculated analyzed. Both explosion unloading earthquake results showed that generally stable state. Thus, this study can provide technical support guidance for mine blasting.
