Abstract

To ensure the safety of mine blasting, reduce the disturbance to residents and ascertain the maximum tolerant explosive quantity of single shot, based on the field test, an analysis of the acquired plentiful practical testing data by least- square analysis is carried out according to Sadaovsky empirical formula,a ttenuation coefficient α and factors co- efficient K of seismic wave are acquired, and the attenuation empirical formula of seismic wave is obtained for the mine. The max single sound detonator quantity could be calculated by the decay experience formula, then determined the burst size,the vibration of the mining area around the building could be controlled in a safe range of speed. The presented re- search achievements have been better applied in the practical project, and satisfactory results are obtained.
