| Abstract (English): | Blasting and drilling methods are mainly used in basalt rock quarries as blasting-digging methods. The purpose of this study is to argue the validity of using a jackhammer as a rock removal method in Gabricar quarry, based on knowing the geomechanical parameters of rocks as well as the technicaleconomic indicators for exploitation. Gravimetric, saturation, hydrostatic weighing, pycnometric and axial loads methods were used to obtain physical-mechanical properties of the rocks and geological survey, volumetric joint count, and strength coefficient were used to establish crack elements, block size, and rock mass quality, respectively. 4.75% humidity; 2.39 % porosity; 5.73 g/cm3 volumetric mass; density of 26.44 g/cm3 and axial compressive strength of 173.53 Mpa as average values of physical-mechanical properties were obtained. Four families of cracks with spacing of 0.4 m, 0.6 m; 0.3 m and 0.2 m and 18 mm openings; 13 mm; 3 mm and 9 mm, respectively were established. Blocks are small and the rocky massif is of good quality. The technical-economic analysis showed the efficiency of the jackhammer as a blasting-based digging method in Gabricar quarry.

| Abstract (Spanish): | En las canteras de rocas basálticas se emplean fundamentalmente métodos de perforación y voladura como métodos de arranque. El objetivo de este estudio fue argumentar la validez del uso de martillo rompedor como método de arranque de rocas en la cantera Gabricar, a partir de conocer los parámetros geomecánicos de las rocas así como los indicadores técnicoeconómicos de explotación. Las propiedades físico-mecánicas de las rocas se obtuvieron mediante los métodos: gravimétrico, de saturación, pesada hidrostática, picnométrico y cargas axiales, y para establecer elementos de las grietas, tamaño de bloques y calidad del macizo rocoso, se emplearon, respectivamente, el levantamiento geológico, recuento de las juntas volumétricas y coeficiente de fortaleza. Se obtuvieron como valores promedios de las propiedades físico-mecánicas, un 4,75 % de humedad; 2,39 % de porosidad; 5,73 g/cm3 de masa volumétrica; densidad de 26,44 g/cm3 y resistencia a comprensión axial de 173,53 Mpa. Se establecieron cuatro familias de grietas con espaciamientos de 0,4 m; 0,6 m; 0,3 m y 0,2 m y aberturas de 18 mm; 13 mm; 3 mm y 9 mm, respectivamente. Los bloques son de pequeño tamaño y el macizo rocoso califica como de buena calidad. El análisis técnico-económico demostró la eficiencia del martillo rompedor como método de arranque en la cantera Gabricar. [ABSTRACT FROM AUTHOR] |
