Consideraciones de
Seguridad en Relaveras
LA MAYORÍA DE LAS operaciones utilizan procesos en húmedo que producen relaves, una mezcla de agua y de partículas minerales. Las operaciones
deben almacenar esta mezcla en sitio, en lagunas, durante suficiente tiempo
para que las partículas de minerales se asienten. Estas lagunas las llamamos
embalses de relaves y relaveras.
El diseño de los embalses de relaves requiere conocimientos de ingeniería. El
propietario debería pensar en involucrar a un ingeniero profesional inscrito con
experiencia en el diseño de represas. El diseño debería cubrir los siguientes temas:
cimiento idóneo, materiales de construcción, tasa de producción de relaves, flujo
de entrada de precipitación y uso de vertederos o bombas para controlar el nivel
de acumulación, percolación y estabilidad de pendientes.
Aunque las represas seguras requieren un buen diseño, es importante que
quienes las construyan tengan cuidado al convertir el diseño en realidad. La preparación adecuada de los cimientos, la colocación y compactación de materiales
de represas y la instalación de tuberías de trasvase juegan un importante papel
en la exitosa conclusión del proyecto. Es crucial seguir los planos constructivos
del diseñador y que el diseñador sea consultado si las condiciones en el campo
son diferentes a las del plan.
Durante el proceso de diseño, debería producirse un manual de operaciones para
regular cómo opera el embalse. Personal calificado debería realizar inspecciones
regularmente durante la construcción y durante la operación para confirmar que
la represa continúe siendo adecuada. También deberían realizarse inspecciones
luego de precipitación severa o de sismos. Mientras el embalse tenga la capacidad
de retener el agua, debe ser inspeccionado regularmente.
