Zusammenfassung: | The invention relates to a cell intended for ground installation, which can be used to identify the geochemical units that form mining waste in order to predict and/or monitor acid draining over time. The cell comprises an outer iron structure that is sandblasted and painted; a lining of structural plywood; an impermeable high-density polyurethane (HDPE) membrane provided on the sides and base of the cell; a third protective layer consisting of a plastic mesh; and, additionally, in the lower part of one of the sides of the cell, at least two PVC (polyvinyl chloride) tubes which pass through holes formed in the plywood and in the impermeable membrane. In addition, the invention relates to the ground installation system and method, said system comprising two cells placed parallel to one another.
Celda para instalar en terreno, que permite identificar las unidades geoquímicas que componen los residuos mineros con el fin de predecir y/o monitorear el drenaje ácido en el tiempo, que comprende una estructura externa de fierro arenada y pintada; un revestimiento interior de madera terciada estructural, y una membrana impermeable de poliuretano de alta densidad (HDPE) provista en los lados y en la base de la celda, y una tercera capa de protección que consiste de una malla plástica; y adicionalmente, en la parte inferior de uno de los lados de la celda se instalan al menos 2 tuberías de PVC (cloruro de polivinilo) las cuales pasan a través de unos orificios hechos en la madera terciada y en la membrana impermeable. Además, se describe el sistema y el procedimiento para instalar en terreno, donde el sistema comprende dos celdas ubicadas en forma paralela. |
