Abstract: El presente documento aborda el tema relacionado a la mecánica de los flujos de relaves en canales abiertos, ya que este sistema de transporte de residuos mineros es el más usado en la industria minera nacional. Los problemas intrínsecos en las actividades mineras relacionadas al manejo de relaves se originan con el desconocimiento parcial o total del comportamiento mecánico y reológico de este tipo de mezclas. Estos problemas pueden ser desde procedimientos de manejo, protocolos de seguridad, impacto ambiental, técnico e ingenieril, traduciéndose todo esto en un problema económico debido al gran costo que se tiene que pagar por la falta de criterios y conocimiento de la mecánica de relaves. Por tal motivo, esta investigación busca profundizar el conocimiento de la relación de las características físicas (concentración) del relave, las condiciones de transporte del canal (pendiente y ancho de la base de canal) y la velocidad del movimiento del relave (mecánica).
Para lograr el objetivo se diseñó y construyó un canal de investigación denominado "Canal de geometría y pendiente variables para flujos bifásicos”.
La versatilidad del equipo experimental permitió generar una matriz de ensayos con diferentes condiciones de ancho y pendiente del canal, que a su vez fueron combinadas con muestras de relave a diferentes concentraciones de sólidos. El equipamiento complementario del canal es un sistema de registros de cámaras de circuito cerrado de televisión (CCTV), con los cuales se obtiene el registro fílmico de los ensayos de los flujos de relaves bajo las condiciones establecidas.
This document addresses the topic related to the mechanics of tailings flows in open channels. This mining waste transport system is the most used in the national mining industry. The intrinsic problems in mining activities related to tailings management have their origin in the partial or total ignorance of the mechanical and rheological behavior of this type-of mixtures. These problems can be due to handling procedures, safety protocols, environmental, technical and engineering impact. AH this translates into an economic problem due to the high cost that has to be paid for the lack of criteria and knowledge of tailings mechanics. Therefore, this research seeks to deepen the knowledge of the relationship between the physical characteristics (concentration) of the tailings, the transport conditions of the channel (slope and Width of the channel base) and the speed of movement of the tailings (mechanical). To achieve the objective, a research channel called "Variable geometry and slope channel for biphasic flows" was designed and built. The versatility of the experimental equipment allowed generating a matrix of tests with different width and slope conditions of the channel, which in turn were combined with samples of tailings at different concentrations of solids. The channels complementary equipment is a closed-Circuit television (CCTV) camera recording system. With this equipment the filming of tailings flow tests is obtained under the established' conditions.
