Abstract: La unidad minera Cerro Lindo del Grupo Milpo, desde los comienzos de su operación en el 2007, ha venido incrementado su producción de manera sostenida, año a año. Para el ejercicio del 2014 la producción será de 15,000 tpd, lo que representa 50% de incremento, con respecto al año anterior, culminando un 300% de incremento con relación a su etapa inicial.
Como resultado de lo anterior se vienen suscitando eventos imprevistos que dificultan la operación, sobre todo, en el proceso de transporte de mineral a planta concentradora, por un tema de desborde de holguras en algunos elementos de la infraestructura que no han sido redimensionados al mismo ritmo de los incrementos de producción.
La Gerencia de operaciones consciente de los mismos efectos en otros elementos de la infraestructura, requiere la identificación de las áreas más afectadas a fin de tomar decisiones dependiendo de un diagnóstico. En ese sentido se realizó un análisis de la cadena del flujo operativo para la explotación de mina y concentración de mineral, determinándose tres aspectos importantes, a tomarse en cuenta.
El proceso de chancado y transporte de mineral
Capacidad de almacenamiento de concentrados
Vida del Botadero 100, de desmonte
En el chancado y transporte de mineral se identifican dos momentos de ocurrencia, el operativo actual o de coyuntura y la visión a largo. Se exponen tres alternativas posibles, adicionales a la actual.
El aumento de producción también trae consigo el aumento de radio crítico de la producción de concentrados lo que ha disminuido la autonomía de tratamiento de la planta concentradora. Se considera contar con una autonomía de la planta concentradora para almacenar concentrados al menos 18 días de operación, en previsión de la paralización de transporte de concentrados por interrupción de vías por problemas diversos de accesibilidad, de mina al puerto del callao, después de un análisis de factores de riesgos, se concluye que son factores con alta probabilidad de ocurrencia. Sin la posibilidad de ampliar el área del depósito actual, por falta de espacio, se recomienda contar con un depósito adicional y se propone tres posibles ubicaciones.
Actualmente el desmonte extraído se deposita en el Botadero-100, este botadero fue concebido y diseñado para un volumen de producción de 10,000 tpd. Con la nueva meta de producción, la vida del botadero se reduce en 20% por lo cual se debe reemplazar a finales del 2015. La premisa fundamental para el reemplazo, en lo posible, debe ser sustentable para toda la vida de la mina, guardando niveles de costos operativos con estándares actuales. Se evalúan tres alternativas de ubicación del botadero reemplazante.
The Mining unit Milpo Group, Cerro Lindo, from the beginning of its operation, in 2007, the production mine has increased steadily, year after year. For the year 2014 the production rate will be 15,000 tons per day, representing 50% over the previous year, ending a 300% increase compared to the initial stage. As a result has been raising unexpected events that hindering the operation, especially in the transportation process to ore concentrator, because of slack overflow in the infrastructure which doesn’t has been resized at the same rate of increases in ore production. Operations management aware of the same effects on some infrastructure important elements, requires the identification of the most affected areas and make decisions about that emerge diagnosis. In that sense, an analysis was made to determine the operational flow chain difficulties for mine production and ore concentration. As a result it determined three aspects to be taken into account, affected by increased production. The Process of ore crushing and conveying. Storage capacity of the concentrate deposit Life of the waste dump Botadero-100 In the ore crushing and conveying process identifies two moments of occurrence, the current operating situation or by the requirements of the recent increase in production and the medium-term vision and life of mine. In the future the largest mining area will be lower than the 1820 level. The tipper haulage ramp means increased costs, ventilation requirements and constant exposure to risk carrying flow interruptions due to accidents or damage equipment on the tracks. It outlines three possible alternatives in addition to the current. Increased production also brings critical radius increased concentrate production, which has reduced the autonomy of the concentrate plant treatment. It is considered to have a range of the concentrator to store concentrated at least 18 days of operation, in anticipation of the cessation of transport of concentrates by road disruption causes of natural phenomena climate, accessibility issues Callao’s Harbor, social unrest or anti- mining, etc. After a risk factors analysis, We concluded that those factors are with occurrence high probability. Without the possibility of extending the current deposit area, for space lack, it is recommended the construction of an additional deposit and proposes three possible locations. Currently the mined waste is deposited in the Dump-100, This dump was thought and designed for a 10,000 tpd production volume. With the new production target, the waste dump life is reduced by 20%, which should be replaced in late 2014. The basic premise for replacement, if possible, should be sustainable for the life of mine, keeping operating costs levels with current standards. It’s estimated replacement dump to be stored about 3.0 million m3 waste. It evaluates three alternative replacement dump locations.
