La Cartographie de la carrière d’agrégat de (E.N.O.F) (Dj.gustar, W. Sétif, Algérie) pour une meilleure orientation d’exploitation

Abstract

The massif of Djebel Gustar belongs to the alloctone south setifiian field .it is contains only a few species of vegetal and animals due to the similarity arid climate, also there is a low hydraulic network.-The aim of our work is to update the cartography of the career sector for a better orientation of exploitation. -The massif of Djebel Gustar is an anticlinal elongated East to the west ,it’s built by carbonate formations (Jurassic- cretaceous) ages covered of parties is by quaternary The study site (career)is located on the south pouring ,crossed by a fissured and crushed zone contenting fissures and fractures direct NE-SW and NW-SE, they have a great effect on mining methods . The cartography of study site description chow by carbonates formations crétacé age (lower aptian and upper aptian age) which are actually exploited by open –pit method in order the produce aggregates.The study of chemical composition and geotechnical analysis carbonates allowed us to establish that carbonates are of good quality An estimate of the reserve has been done by the method of geological cuts
