Abstract

SE REFIERE A UN METODO PARA CARGAR UN BARRENO, QUE SE EXTIENDE ENTRE UNA BOCA DEL MISMO EN UNA SUPERFICIE Y UN EXTREMO O FONDO CIEGO DEL MISMO DISTANTE DE LA BOCA, QUE COMPRENDE: 1)PROPORCIONAR, EN EL BARRENO, A UN NIVEL RELATIVAMENTE BAJO HACIA DICHO FONDO, UNA CAPA INFERIOR DE UNA SUSTANCIA EXPLOSIVA (i) Y UNA CAPA INFERIOR DE UN MATERIAL DE EMBOLO (ii) DIRECTAMENTE SOBRE OTRA CAPA (i); 2)PROPORCIONAR, EN EL BARRENO, A UN NIVEL RELATIVAMENTE ALTO DISTANTE DE DICHO FONDO, UNA CAPA SUPERIOR DE UN MATERIAL DE EMBOLO (iii), ESPACIADA A UNA DISTANCIA DETERMINADA SOBRE LA CAPA (ii) Y, DIRECTAMENTE SOBRE (iii), UNA CAPA SUPERIOR DE UNA SUSTANCIA EXPLOSIVA (iv); 3)COLOCAR INICIADORES EN ASOCIACION CON LAS RESPECTIVAS CAPAS DE SUSTANCIAS EXPLOSIVAS Y CONECTARLOS A UN CONTROLADOR PARA ACTIVARLOS A INTERVALOS DE TIEMPO PREDETERMINADOS; DONDE, EL ESPACIAMIENTO ENTRE LAS SUPERFICIES OPUESTAS DE, (ii) Y (iii), ES ENTRE 0,5 m Y 3 m Y LAS CAPAS RESPECTIVAS DE MATERIAL DE EMBOLO SON DE UN MATERIAL FLUYENTE QUE PERMITE SU COLOCACION EN EL BARRENO, EN LAS POSICIONES DESEADAS RESPECTIVAS.REFERS TO A METHOD FOR LOADING A HOLE, WHICH EXTENDS BETWEEN A MOUTH OF THE SAME IN A SURFACE AND A BLIND END OR BOTTOM OF THE SAME DISTANCE FROM THE MOUTH, WHICH INCLUDES: 1) PROVIDE, IN THE HOLE, AT A RELATIVELY LOW LEVEL TOWARDS SAID BACKGROUND, A LOWER LAYER OF AN EXPLOSIVE SUBSTANCE (i) AND A LOWER LAYER OF A PACKING MATERIAL (ii) DIRECTLY OVER ANOTHER LAYER (i); 2) PROVIDE, IN THE HOLE, AT A RELATIVELY HIGH LEVEL AWAY FROM SAID BACKGROUND, A TOP LAYER OF A PACKING MATERIAL (iii), SPACED AT A DETERMINED DISTANCE ABOVE THE LAYER (ii) AND, DIRECTLY OVER (iii), A TOP LAYER OF AN EXPLOSIVE SUBSTANCE (iv); 3) PLACE INITIATORS IN ASSOCIATION WITH THE RESPECTIVE LAYERS OF EXPLOSIVE SUBSTANCES AND CONNECT THEM TO A CONTROLLER TO ACTIVATE THEM AT PRE-DETERMINED TIME INTERVALS; WHERE, THE SPACING BETWEEN THE OPPOSITE SURFACES OF, (ii) AND (iii), IS BETWEEN 0.5 m AND 3 m AND THE RESPECTIVE LAYERS OF PACKING MATERIAL ARE OF A FLOWING MATERIAL THAT ALLOWS THEIR PLACEMENT IN THE HOLE, IN THE RESPECTIVE DESIRED POSITIONS.
