Abstract
EL CORTE HORIZONTAL DE MAQUINAS DE EXTRACCION COMO MAQUINA CEPILLADORA DE CARBON Y CARGADORES DE RODILLOS PARTICULARMENTE LA SITUACION DE LA CAPA LIMITE DE ROCAS DE CARBON PUEDE ABARCARSE CON AYUDA DE LONGITUDES DE ONDA SELECCIONADAS DE SEÑALES DE LUZ EN CAPAS DE REFLESION. EN LA MAQUINA DE EXTRACCION SE DISPONE UN SENSOR PRINCIPAL GUIADO Y MOVIENDOSE SOBRE EL YACIMIENTO CON UN HAZ DE ONDAS DE LUZ CONFORMADO COMO REGISTRADOR DE VALAOR Y GUIADO EN UN CANAL CERRADO CON UNA VENTANA DE CRISTAL. EN LA MAQUINA SE DISPONE UNA ESTACION DE EMISION Y RECEPCION. PARA LA IDENTIFICACION CLARA DE LA CAPA LIMITE DE ROCAS DE CARBON EL CANAL (6) QUE REGISTRA EL HAZ (5, 5'') DE ONDAS DE LUZ A LA SALIDA DEL SENSOR PRINCIPAL (3) MARCHA CON ANGULO DE 30 SOBRE EL YACIMIENTO Y LA SUPERFICIE INTERIOR (13) DE LA VENTANA DE CRISTAL (7) TRANSCURRE PARALELAMENTE AL YACIMIENTO.
