Abstract

El aparato incluye una hoja flexible que incluye un par de bordes laterales separados que se extienden longitudinalmente y un par de bordes de extremo separados que se extienden lateralmente. La hoja tiene una forma curvada que define un pasaje longitudinal que se extiende entre aberturas en extremos longitudinalmente opuestos, siendo un extremo de la hoja curvada insertable dentro del extremo abierto de un barreno mediante lo cual la hoja curvada enfrenta estrechamente una superficie interna del barreno y forma una barrera que evita que los fragmentos circundantes de roca sueltos caigan o colapsen dentro del barreno. También se provee un método de voladura en banco y un dispositivo de despliegue para desplegar el aparato dentro de un barreno.The apparatus includes a flexible sheet that includes a pair of spaced longitudinally extending side edges and a pair of spaced apart laterally extending end edges. The blade has a curved shape defining a longitudinal passageway extending between openings at longitudinally opposite ends, one end of the curved blade being insertable within the open end of a bore whereby the curved blade closely faces an internal surface of the bore and forms a barrier that prevents surrounding loose rock fragments from falling or collapsing within the hole. A bench blasting method and a deployment device are also provided for deploying the apparatus into a borehole.
