Abstract

Un método de desarrollo de pozos subterráneos que comprende: (a) perforar barrenos que se extienden hacia el interior de una formación rocosa, donde cada barreno se perfora a partir de un punto inicial que define un primer extremo del barreno hasta un punto final que define un segundo extremo del barreno; (b) cargar los barrenos con capas alternadas de cargas de explosivos y material de retacado para producir múltiples pisos de voladura a través y hacia el interior de la formación, que incluyen por lo menos un primer piso de voladura correspondiente a los primeros extremos de los barrenos y un piso de voladura final que corresponde a los segundos extremos de los barrenos, donde cada piso de voladura sostiene dispositivos de voladura inalámbricos; y (c) detonar las cargas de explosivos en una serie de etapas de voladura basadas en los pisos de voladura mediante la activación de los dispositivos de voladura inalámbricos en cada piso de voladura, procediendo en forma sucesiva a partir del primer piso de voladura hasta el piso de voladura final, donde después de cada etapa de voladura se produce la excavación para la prolongación del pozo en una dirección pretendida.An underground well development method that comprises: (a) drilling holes that extend into a rock formation, where each hole is drilled from an initial point that defines a first end of the hole to an end point that defines a second end of the hole; (b) loading the holes with alternating layers of explosive charges and retouching material to produce multiple blasting floors through and into the formation, which include at least a first blasting floor corresponding to the first ends of the holes and a final blasting floor that corresponds to the second ends of the holes, where each blasting floor supports wireless blasting devices; and (c) detonate explosive charges in a series of blasting stages based on blasting floors by activating wireless blasting devices on each blasting floor, proceeding successively from the first blasting floor to the final blasting floor, where after each blasting stage excavation takes place for the extension of the well in an intended direction.
