Abstract

Un método de voladura de roca, en minería para material recuperable, que comprende perforar barrenos de voladura en una zona (1) de voladura, cargar los barrenos de voladura con explosivos y luego encender los explosivos en los barrenos de voladura en un ciclo individual de perforación, carga y voladura. La zona de voladura comprende una zona de voladura de alta energía en la que se cargan parcialmente barrenos (2) de voladura con un primer explosivo (5) para proporcionar una capa de alta energía de la zona de voladura de alta energía que tiene un factor de carga de al menos 1,75 kg. de explosivo por metro cúbico de roca no sometida a voladura en la capa de alta energía y en la que al menos algunos de esos barrenos de voladura también se cargan con un segundo explosivo (6) para proporcionar una capa de baja energía de la zona de voladura de alta energía entre la capa de alta energía y el extremo adyacente de esos barrenos de voladura, teniendo dicha capa de baja energía un factor de carga que es al menos un factor de dos menor que el factor de carga de dicha capa de alta energía. El método de voladura de alta energía proporciona una fragmentación de roca mejorada a través de un aumento de la concentración de energía de explosivo a la vez que se alivian simultáneamente efectos de voladura perjudiciales para el entorno.
