          Abstract

          Abstract In room and pillar (R&P) mining, the procedures adopted to design mine panels are based on the safety factor (SF) of pillars. For this reason, is so important to study the geological and geomechanical behavior of the areato be mined. The use of a mathematical model allows identifying problematic áreas and to test different configurations in a safe manner. This paper shows the development and application of a flexible and automatic routine to quantify the safety in R&P mining in terms of SF and room convergence (RC). The commercial software package FLAC3D was used to implement a computational routine in FISH language capable of representing in a fast and accurate way the main characteristics of the geomechanical conditions, lithology and geometrical features of a R&P mining project automatically. In order to show the capabilities of the routine developed here, a case of study was performed in a manganese ore mine.

          Resumen En la minería de cámaras y pilares (R&P), los procedimientos adoptados para diseñar los paneles de la mina se basan en el factor de seguridad (SF) de los pilares. Por ello, es tan importante estudiar el comportamiento geológico y geomecánico de la zona que se va a minar. El uso de un modelo matemático permite identificar las zonas problemáticas y probar diferentes configuraciones de forma segura. Este trabajo muestra el desarrollo y la aplicación de una rutina flexible y automática para cuantificar la seguridad en la minería R&P en términos de SF y de convergencia de salas (RC). Se utilizó el paquete de software comercial FLAC3D para implementar una rutina computacional en lenguaje FISH capaz de representar de forma rápida y precisa las principales características de las condiciones geomecánicas, la litología y las características geométricas de un proyecto de minería R&P de forma automática. Para mostrar las capacidades de la rutina aquí desarrollada, se realizó un caso de estudio en una mina de mineral de manganeso.
