Abstract

La metodología busca generar con un doble retardo en la columna explosiva de las perforaciones de un diagrame de disparo, las condiciones para que la roca removida por el explosivo en la primera etapa iniciado con un retardo X, sea expulsada con facilidad hacia el frente de la labor con la voladura de la carga explosiva de la segunda etapa iniciado con un retardo Y, generando un TANDEM; y donde el retardo X tiene un tiempo de activación menor al retardo Y. El objetivo es maximizar el avance efectivo de la tronadura de un diagrama de perforación pera construir túneles o galerías subterráneas en roca horizontales a sub horizontales hecho con tiros largos sobre 4m.The methodology seeks to generate with a double delay in the explosive column of the perforations of a shot diagram, the conditions so that the rock removed by the explosive in the first stage, initiated with a delay X, is easily expelled towards the front of the work with the blasting of the explosive charge of the second stage started with a delay Y, generating a TANDEM; and where the X delay has a lower activation time than the Y delay. The objective is to maximize the effective advance of the blast of a drilling diagram to build tunnels or underground tunnels in horizontal to sub horizontal rock made with long shots over 4m.
