Evaluating the Impact of Vibrations Generated by Blasting in Morocco: Measurements, Prediction, and Mitigation Solutions Using Traditional and Innovative Metamaterials

In Morocco, urban expansion is driving a high demand for construction materials, intensifying mining operations through explosive blasting. These blasts produce seismic and acoustic vibrations that can damage buildings and harm the health of nearby residents. Current mitigation methods are often ineffective, costly, or poorly adapted. This work proposes an innovative solution based on metamaterials, capable of attenuating the propagation of harmful vibrations within specific frequency ranges (< 50 Hz). The approach includes : field vibration measurement campaigns, laboratory geotechnical testing, and numerical simulations to evaluate the effectiveness of metamaterials compared to conventional solutions. The objective is to develop robust, economical, and adapted devices for Moroccan conditions to better control the vibrational nuisances from mining blasts.
