Abstract: Intense vibration induced by deep-hole blasting in stope has a great effect on the stability of the open-pit slope. In order to reduce the negative effects of blasting vibration, it must take the necessary measures and pay enough attention to the stability of open-pit slope in opencast blasting. Research on the blasting earthquake theory, the stability of Sijiaying mining area open-pit slope has analyzed. Meanwhile, it references some blasting vibration of drop earthquake experience at home and abroad, Sijiaying mining area blasting drop earthquake of method has summary and exploration. It takes interval loaded drug, slag blasting, delay blasting, and other blasting drop vibration measures. Combined with Sijiaying mining area site situation, it gives future improved way of depress blasting earthquake.
