Prediction of air-overpressure induced by blasting using an ANFIS-PNN model optimized by GA
2021, Applied Soft ComputingCitation Excerpt :For the probability of structural damages, the AOp needs to be as high as 180 dB; for glass of widows to be broken, between 130 and 150 dB; and for windows to be vibrated, between 110 and 130 dB. As a result, especially in life-threatening and important regions, great efforts are usually made to keep AOp less than 110 dB [16,20,74]. In general, four key sources exist in every blasting operation that generate the AOp waves [75,76]:
Prediction of airblast-overpressure induced by blasting using a hybrid artificial neural network and particle swarm optimization
2014, Applied AcousticsCitation Excerpt :An AOp level of the structural damage possibility is 180 dB, glass break is 130–150 dB, and window vibration is 110–130 dB. Therefore, many attempts are made to keep AOp below 110 dB in critical areas where the public is concerned [9,13,25]. In general, AOp waves are produced from four main sources in blasting operations [26–28]:
Prediction of near field overpressure from quarry blasting
2010, Applied AcousticsCitation Excerpt :The scatter in the a0 coefficients reported by USBM [2] is an example of the directionality of the propagation of blast waves. In fact, the contour curves of equal overpressures from bench blasting have a shape similar to an “egg” curve, longer at the floor level and shorter at the top [7–12]. These azimuthal variations may be reinforced in specific directions depending on the characteristics of the sequence of the blast [2,10,13].
