Evaluación geotécnica del área de Los Aceitunos en la mina de carbón Paso Diablo, municipio Mara, estado Zulia

Abstract

The following work consists a field study, specifically in looking for outcrops that are framed in the area of future terraces in the zone the Aceitunos, from which geotechnical, geological and structural information was obtained, which can to contribute quantitative data that they showed the quality of the present outcrops in the zone, that they will serve for the study and modification as the design as the slopes in the Paso Diablo mine. For this three methods of classification were used (Barton, Bieniawski and Piero Feliziani). In addition, stereographics projections of joints and fold found in the zone were made, with the purpose of knowing predominant structural pattern, with the STEREONET program, public domain. With the measurements in the three piezometers located in the zone, it was come to design in SURFER 8, a piezometric model, showing the water direction like mainly obstacle that goes from the NW to SE. In order to complete this study, profiles located in the zone of the terraces predesigned in the Pit Aceitunos with the purpose of knowing the influence were designed that has the structural pattern in the stability of the future slopes.
