Abstract


In order to study the open-pit mine stope of high bench blasting vibration on slope stability, the influence of the blasting vibration signal test system of a certain open-pit mine stope surrounding high slope blasting vibration monitoring, obtain vibration data, according to Steve Sadove, experience formula and Hilbert Huang transform (HHT) blasting vibration signal analysis method, the attenuation law of blasting vibration on slope, slope was the main vibration frequency of vibration. According to Sadov’s formula, experience formula and Hilbert Huang transform (HHT) analysis results, and on the basis of the blasting safety regulations (GB6722- 2014) for minimum safety distance is 86 m, slope for mining in the aspect of reducing the influence of blasting vibration on slope take corresponding measures to provide a reference basis.
