| description | The filtration of surface and groundwater is very common when mining works is advancing, since underground aquifers, old blocks exploited must be crossed and within the extraction process, a settlement of the strata that produce some range of subsidence and fracture of these is generated, resulting in the filtration of these waters from the surface of the ground to inside of the mines. This wastewater must be evacuated back to the surface, which it is necessary to conduct it throughoutthe mining works (using mechanisms such as ditches, hoses and pipes), tending to contaminate with the environment of mining pollution and the same direct contact with the rocks of the excavations. Once driven to the surface, by means of pumps of great capacity and flow depending on the depth of the work, these wastewaters must be managed in treatment systems in order to perform a cleaning in this case of the concentrations of sediment solids and be able to be discharged to nearby sources, to be reused in processes other than human consumption. The present study evaluated in a technical,economic and environmental way three water treatment alternatives, getting results from alternative 1 Coagulation-Flocculation, an efficiency percentage of 99.12%, a total installation cost of $17,363,978 Colombian money, and a low environmental affectation, simulating with the SuperDecisions® software, that Alternative 1 Coagulation-Flocculation has the ranking number 1, followed by the alternative Activated Carbon with ranking number 2 and, finally the maintenance of the system with ranking 3. |

La filtración de aguas residuales superficiales y subterráneas es muy común cuando se avanzan labores de explotación minera, ya que se deben cruzar acuíferos subterráneos, bloques antiguos explotados y, dentro del proceso de extracción, se genera un asentamiento de los estratos que producen algún rango de subsidencia y fracturamiento, dando lugar a la filtración de estas aguas desde la superficie del terreno al interior de las minas. Las aguas residuales deben ser evacuadas nuevamente hacia la superficie, para lo cual es necesario conducirlas a lo largo de las labores mineras (utilizando mecanismoscomo cunetas, mangueras y tuberías), proceso que tiende a contaminar el ambiente de polución minera, inclusive, con el contacto directo de las rocas de las excavaciones. Una vez conducidas a la superficie, por medio de electrobombas de gran capacidad y caudal, y dependiendo de la profundidad de las labores, estas aguas residuales deben ser manejadas en sistemas de tratamiento con el fin de realizar una limpieza, en este caso de las concentraciones de sólidos sedimentables y poder ser vertidas a las fuentes cercanas, para ser reutilizadas en procesos diferentes al consumo humano. El presente estudio evaluó de manera técnica, económica y ambiental, tres alternativas de tratamiento de aguas, donde se obtuvoresultados de la alternativa 1 Coagulación-Floculación, un porcentaje de eficiencia del 99,12%, un costo total de instalación de $17’363.978 pesos y una afectación ambiental baja, simulado con el software SuperDecisions® que la Alternativa 1 Coagulación-Floculación tiene el ranking número 1, seguido de la alternativa Carbón Activado con ranking número 2 y, por último, el mantenimiento del sistema con ranking 3.
