CONSTRUCTION SECURITY WITH RESPECT TO MINESHOOTING VIBRATIONS

Natural vibration sources are multiple. Those due to the explosions of mine can be dangerous. During he fracture a considerable energy propagated in the form of seismic waves generating a series of vibratory movements on the ground surface witch are transmitted to the constructions trough the foundations. The aim of this paper is to study the effects of the vibrations due to the shootings of mine of the quarriers Socar and Altro companies located at Mechta Bouzitoune on neighbouring constructions of the city Elwième, 50 residences at Héliopolis, in the east of Algeria, which are characterized by the appearance of the cracks in the masonry walls on all the height of the buildings. It resides in the determination of the acceptable explosive load, particulate speed threshold, the radius of safety and the level of the vibrations on the level of constructions for compared with the principal standards and international recommendations.
