OPTIMIZATION OF BLASTING PARAMETRS IN OPEN CAST QUARRIES OF EL HASSA-BOUIRA (NORTHERN ALGERIA)
Main Article Content
Abstract
In recent years, Algeria has known a rapid growth in the construction projects, such as buildings, roads, and infrastructure, which increased the demand for aggregates production in quarries. However, vibrations and noises generated by blasting operations have a negative impact on the residents living nearby. For this reason, blast tests were performed in the open cast quarries of the company Sarl El Hassa-Bouira (Northern Algeria) using instantaneous electric detonators (IED), micro delays (MDD) and delays (EDD) to minimize the instantaneous load. We also minimized noise and vibration during the blasting. A seismograph allowed us to take further measurements.
Keywords: Quarry, blasting, seismic and acoustic vibrations, electric detonators, rock fragmentation.
