Resumen

En los últimos años y debido al aumento de la actividad minera, se ha incrementado el número de eventos que han traído consigo roturas catastróficas y súbitas en los depósitos de residuos, con pérdida de numerosas vidas humanas. En muchos casos se ha interpretado que la causa principal de estos fallos ha sido la licuación por flujo. El presente documento tiene como finalidad aproximar el campo teórico y el práctico a la hora de realizar un diseño y/o para evaluar un depósito existente o en construcción. De esta manera se pretende que cualquier ingeniero que no sea experto en la materia pueda comprender el fenómeno de la licuación por flujo y analizar de forma crítica el diseño de un depósito de residuos mineros. Su diseño, sin embargo, debería quedar reservado a los ingenieros con experiencia en el tema.
