EXPLOITATION DE LA ROCHE ORNEMENTALE DE DJEBEL LABIODH (WILAYA DE TLEMCEN)

Abstract

The Sidi Abdelli unit exploits a deposit of ornamental stones, which consists of micritic limestones, dolomitic limestones, and dolomites. This study highlights the relationship between fracturing and the direction of exploitation, showing how this tectonic parameter controls the recovery rate of marketable blocks from the extracted mass. To achieve this objective, an in-depth analysis of the cycle times for each extraction process was conducted. This allowed for the identification of critical phases where fractures impact efficiency. In parallel, the efficiency of each extraction method was evaluated to determine which one maximizes stone recovery while minimizing losses due to fractures. The best extraction techniques were selected considering both operational efficiency and associated costs. Innovative approaches, including advanced sawing methods, the use of block stabilization technologies, and proactive fracture risk management strategies, were adopted. This study emphasizes the importance of optimizing extraction methods in ornamental stone deposits to ensure sustainable and profitable exploitation. By effectively addressing the challenges posed by fractures, the Sidi Abdelli unit aims to enhance its market competitiveness while preserving natural resources and meeting the growing demand for high-quality stones.
