Abstract:
With the increasing pursuit of a better life by the public,mining operations need to pay more attention to the adverse effects of blasting vibrations on people and buildings (structures).Based on the measured blasting vibration data in Huibaoling Iron Mine,the attenuation law of blasting vibrations in mines was studied using the Sadaovsk empirical formula.The analysis focused on determining the safe distance for blasting vibrations and identifying the reasonable maximum segment explosive quantity for different mid-section mining operations.This study provides theoretical basis and guidance for the safe mining operations in the mine.The results indicate that there are no safety issues with blasting vibrations for buildings located beyond 1 197.21 m from the working face,while protective objects within the mining area should be positioned approximately 400-500 m away from the blast source.To achieve the peak velocity target of 0.2 cm/s for blasting vibrations,the allowable maximum segment explosive quantity should be controlled at around 200 kg.
