Diseñar una malla de perforación y voladura de rocas en minería subterránea conllevó analizar el relacionamiento de variables medibles para mejorar el avance de labores mineras. La selección de los parámetros del diseño de la malla de perforación fue fundamental en los resultados de avance de labores mineras. Un indicador de la calidad de rotura fue determinar el factor de seguridad con un nivel de estabilidad mayor a la unidad en las paredes de la sección minera. En el análisis también se consideró el porcentaje de fragmentación como un indicador de calidad de la voladura para satisfacer la necesaria fase de carguío y acarreo del material a su destino final. La recolección de datos en la unidad de análisis considerada en la investigación aportó valores típicos, medibles y reproducibles de la reducción de la sobre rotura y aumento de la fragmentación de roca que con...

De manera que, el objeto del presente estudio es conocer el estado actual del contrato psicológico y su relación con el desempeño y la satisfacción en 303 empleados del sector público y privado de Lima. Los resultados nos indican que existe una correlación significativa y positiva entre el contrato psicológico, el desempeño y la satisfacción.
