“…Drilling and blasting is one of the most common, economical, and efficient technologies, and it has been widely utilized in rock mass excavation and engineering construction applications. However, the use of such techniques in engineering practices has also raised considerable engineering stability and safety issues for researchers all over the world [1][2][3]. Understanding the dynamic fracturing behavior of rock as a heterogeneous material under blasting loading has important implications for both realizing more efficient rock breakage and preservation of rock masses.…”

In this paper, an internal central single-cracked disk (ICSCD) specimen was proposed for the study of dynamic fracture initiation toughness of sandstone under blasting loading. The ICSCD specimen had a diameter of 400 mm sandstone disc with a 60 mm long crack. Blasting tests were conducted by using the ICSCD specimens. The blasting strain-time curve was obtained from the radial strain gauges placed around the blast hole. The fracture initiation time was determined by circumferential strain gauges placed around the crack tip. The stress history on the blast hole of the sandstone specimen was then derived from measured strain curve through the Laplace transform. The numerical solutions were further obtained by the numerical inversion method. A numerical model was established using the finite element software ANSYS. The type I dynamic stress intensity factor curves of sandstone under blasting loading were derived by the mutual interaction integration method. The results showed that (1) the ICSCD specimen can be used to measure dynamic initiation fracture toughness of rocks; (2) the stress on the blast hole wall can be obtained by the Laplace numerical inversion method; (3) the dynamic initiation fracture toughness of the ICSCD sandstone specimen can be calculated by the experimental-numerical method with a maximum error of only 7%.

En la cantera de árido de estudio se extrae roca caliza para su explotación como material de construcción. La función principal de las voladuras de producción es obtener mediante el uso de explosivos civiles, un tamaño de bloque adecuado para la planta de trituración, conseguir un frente de talud estable, bien marcado y rectilíneo para garantizar la estabilidad de la explotación y minimizar las vibraciones en las estructuras y zonas de interés circundantes. Para ello se define una voladura tipo en la que se simulan y evalúan los principales parámetros de diseño mediante el uso del software JKSimBlast, un perfilómetro 2D y dos sismógrafos, buscando conciliar una producción óptima con un nivel mínimo de vibraciones en las zonas a monitorear. AbstractAt the studied quarry, limestone is extracted for its exploitation as construction material. The main functions of production blasts are to obtain, by using civil explosives, a suitable block size for the crushing plant, to achieve a stable, well-marked and rectilinear slope, to guarantee the stability of the operation and to minimize the vibrations in the surrounding structures and areas of interest. For this, a type blast is defined in which the main design parameters are simulated and evaluated using JKSimBlast software, a 2D profiler and two seismographs, seeking to reconcile optimal production with a minimum level of vibration in the areas to be monitored.
