Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Resumen Se realizó una caracterización geomecánica de un túnel guía para la explotación de oro en la mina Yaraguá (Continental Gold Limited) en el Municipio de Buriticá (Antioquia). El proceso de caracterización comprendió la clasificación del macizo rocoso mediante los sistemas de clasificación RMR y Q, análisis de secciones delgadas, ensayos de velocidad de ondas P, carga puntual simple y resistencia a compresión uniaxial y triaxial. Las rocas analizadas se clasificaron como basaltos, andesitas, dioritas y brechas, todas con minerales como magnetita, carbonatos y de pirita. En los ensayos de velocidad de ondas, las rocas alcanzaron un 70% de la velocidad teórica, mostrando índices de continuidad que están en el intervalo de fuerte a intermedia. La resistencia a compresión uniaxial en el intervalo de 42 MPa y 134 MPa. El comportamiento de las rocas bajo las cargas en el ensayo de compresión triaxial muestra una tendencia frágil a frágil-dúctil y con una resistencia máxima en el intervalo de 130 MPa a 150 MPa. A partir de todos estos ensayos se determinó que hay dos tipos de fallamiento asociado a la mineralización: ya sea a través de venillas o por zonas de acumulación de sulfuros.
