Abstract

UN EQUIPO PARA PERFORAR ROCA (1) ESTA PROVISTO DE UNA MAQUINA PERFORADORA DE ROCA (6) QUE COMPRENDE UN DISPOSITIVO DE IMPACTO (4), UN DISPOSITIVO ALIMENTADOR (9) Y UNA HERRAMIENTA (7) CON UNA BROCA (8) EN EL EXTREMO DE ESTA PARA ROMPER LA ROCA. EL DISPOSITIVO DE IMPACTO ESTA DISPUESTO PARA PRODUCIR UNA ONDA DE ESFUERZO EN LA HERRAMIENTA Y QUE CONTINUA DESDE ELLA HASTA LA ROCA QUE SE VA A PERDORAR. DURANTE LA PERFORACION POR LO MENOS UNA PARTE DE LA ONDA DE ESFUERZO DE COMPRESION (OI) CAUSADA EN LA HERRAMIENTA ES REFLEJADA COMO UNA ONDA DE ESFUERZO (OR) QUE VUELVE DESDE LA ROCA HACIA LA HERRAMIENTA. EL METODO COMPRENDE DETERMINAR EL IMPULSO (PR) DE LA ONDA DE ESFUERZO (OR) REFLEJADA DESDE LA ROCA HACIA LA HERRAMIENTA Y AJUSTAR LA OPERACIÓN DEL DISPOSITIVO DE IMPACTO Y/O AQUELLA DEL DISPOSITIVO ALIMENTADOR BASANDOSE EN EL IMPULSO.A ROCK DRILLING EQUIPMENT (1) IS EQUIPPED WITH A ROCK DRILLING MACHINE (6) INCLUDING AN IMPACT DEVICE (4), A FEEDING DEVICE (9) AND A TOOL (7) WITH A DRILL (8) AT THE END OF THIS TO BREAK THE ROCK. THE IMPACT DEVICE IS DESIGNED TO PRODUCE A WAVE OF EFFORT ON THE TOOL AND THAT CONTINUES FROM IT TO THE ROCK THAT IS GOING TO BE LOST. DURING DRILLING AT LEAST A PORTION OF THE COMPRESSION STRESS WAVE (OI) CAUSED IN THE TOOL IS REFLECTED AS A STRESS WAVE (OR) RETURNING FROM THE ROCK TOWARDS THE TOOL. THE METHOD INCLUDES DETERMINING THE IMPULSE (PR) OF THE STRESS WAVE (OR) REFLECTED FROM THE ROCK TOWARDS THE TOOL AND ADJUSTING THE OPERATION OF THE IMPACT DEVICE AND / OR THAT OF THE FEEDING DEVICE BASED ON THE IMPULSE.
