Abstract
Luego de 105 años de vida productiva, la mina El Teniente experimenta hoy el agotamiento de los sectores que actualmente se encuentran en explotación, lo que le exige avanzar hacia una nueva fase de profundización, con el objetivo de extender su operación y asegurar el cumplimiento de las metas de producción programadas por la Corporación. En este marco es que, en el año 2011, se aprobó la ejecución del Proyecto Nuevo Nivel Mina, cuyo objetivo es explotar las reservas de mineral ubicadas 300 metros más profundo que los niveles actuales de explotación de la mina El Teniente, otorgando continuidad operacional a la División. Tras dificultades presentadas durante la construcción del Proyecto, es que nace el Proyecto Nuevo Nivel Mina Andes Norte, el cual considera en primera instancia la explotación de solo un sector del Nuevo Nivel Mina denominado Andes Norte, acompañado de otras dos nuevas minas. Una vez consolidad la explotación de la mina Andes Norte el año 2032 comienza una segunda etapa de expansión al resto de minas para completar las reservas del proyecto original, lo que permitirá mantener los niveles de producción de la División El Teniente por los próximos 50 años.
En la construcción subterránea de las obras de excavación del Proyecto Nuevo Nivel Mina Andes Norte (PNNM-AN) se presentan constantes pérdidas operacionales y desperdicios de recursos, los cuales no alcanzan ser controlados, debido a que solo se logra obtener una visualización operacional localizada y se cuenta con poca información sobre lo que ocurre en las operaciones durante el desarrollo del turno, y cualquier desviación presentada durante el turno es detectada al final de este, sin tener la posibilidad de corregirlo en el mismo instante evitando cualquier desperdicio. En este marco es que la Vicepresidencia de Proyectos de Codelco está desarrollando un Sistema de Monitoreo en Línea (SML) de las obras de excavación de la construcción subterráneas del PNNM-AN, con el objetivo de aumentar la productividad, optimizar el uso de recursos y mejorar los niveles de seguridad.
De acuerdo con lo anterior, es que en este trabajo se han establecidos los requerimientos básicos del SML respecto a la información clave que debe capturar, procesar y desplegar en la sala de control de operaciones. Para esto, primero se identificaron los problemas y causas de las pérdidas operacionales con mayor frecuencia e impacto en el desarrollo del Proyecto, enfocado en la búsqueda de oportunidades de mejora que pudiesen ser abarcadas por el SML, tales como el mejoramiento de la planificación, comunicación y coordinación de las actividades desarrolladas durante el turno, así como también el mejoramiento del uso de los recursos disponibles y la disponibilidad de los equipos. A partir de las oportunidades de mejora identificadas se entregaron distintas soluciones a partir de la información que podría proporcionar el SML, determinado finalmente que para obtener esta información es necesario monitorear a través del SML las distintas frentes de trabajo, las personas en faena y todos los equipos involucrados en el ciclo de avance
After 105 years of productive life, the mine “El Teniente” is currently experiencing the depletion of the sectors that are currently in operation, which requires it to move towards a new deepening phase, with the aim of extending its operation and ensuring compliance with the production goals programmed by the Corporation. Within this framework, in 2011, the execution of the Project "Nuevo Nivel Mina" was approved, whose objective is to exploit the mineral reserves located 300 meters deeper than the current levels of exploitation of the mine "El Teniente", granting operational continuity to the division. After difficulties presented during the construction of the Project, the Project "Nuevo Nivel Mina" was born, which considers in the first instance the exploitation of only a sector of the "Nuevo Nivel Mina" called the "Andes Norte", accompanied by two other new mines. Once the exploitation of the mine "Andes Norte" is consolidated, in 2032 a second stage of expansion begins to the rest of the mines to complete the reserves of the original project, which will allow the production levels of the "División El Teniente" to be maintained for the next 50 years. In the underground construction of the excavation works of the Project "Nuevo Nivel Mina Andes Norte", there are constant operational losses and waste of resources, which cannot be controlled, since only a localized operational visualization is obtained and little information is available about what happens in operations during the development of the shift, and any deviation presented during the shift is detected at the end of this, without having the possibility of correcting it at the same time avoiding any waste. In this framework, the Vicepresidencia de Proyectos de Codelco Chile is developing a "Sistema de Monitoreo en Línea" (SML) of the excavation works of the underground construction of the project "Nuevo Nivel Mina Andes Norte", with the objective of increasing productivity, optimizing the use of resources and improve security levels. In accordance with the above, it is that in this work the basic requirements of the SML have been established regarding the key information that must be captured, processed and displayed in the operations control room. For this, the problems and causes of operational losses with the highest frequency and impact on the development of the Project were first identified, focused on the search for improvement opportunities that could be covered by the SML, such as the improvement of planning, communication and coordination of the activities carried out during the shift, as well as improving the use of available resources and the availability of equipment. From the identified improvement opportunities, different solutions were delivered based on the information that the SML could provide, where it was finally determined that to obtain this information it is necessary to monitor through the SML the different fronts, people and work teams involved in the advance cycle
