  • Mine
    • To have the visualization of mine operation signals that allows to monitor ore production from any location. Previously, visualization was only possible in the Control Room on an HMI interface that connected to the PLC and was limited to signals.
    • To have various automatic production calculations such as asset hourmeters. Previously, counting was done manually on paper.

  • Plant
    • Relate plant signals in the PI AF tree to handle the same standard with the SAP PM structure.
    • Development of automatic reports using PI DataLink for plant production, combining operational signals and grades.
    • Design of deployments in PI Vision for operational monitoring of all plant processes, development of calculations and notifications to obtain real time production and alerts.
  • Lima
    • Another important requirement was to have the relevant operational information of each of the units centralized in a Corporate Server located in the city of Lima and the generation of metallurgical balances, for which the implementation of PI to PI interfaces was defined, allowing the sending of production information from the plants to the Corporate PI Server and from there, the grade information to each of the units, considering that the application used by Minas Buenaventura to store its grades is located in the Lima network.
  • Solución
  • PI System architecture design
    • The PI System architecture was designed by our team of specialists considering the communication requirements of Minas Buenaventura for each of the units. The integration of all identified information sources and the type of OSIsoft interface used in each of them was considered. For example, Modbus type interfaces to make the connection with PLCs equipment of the skips in the Mine area, OPC DA type interfaces to make the connection with the Scada systems in the Plant area, RDBMS type interfaces for the connection to relational database in the Laboratory and Energy area.
  • PI System Installation
    • The main PI System servers were installed and configured, such as PI Data Archive, PI AF Asset framework and PI Vision, in each of the mining units in order to have faster responses and reduce information latency, considering hardware resources for information storage for a period of 5 years. A total of 28 interfaces (API Nodes) required to collect information from data sources were configured. For the management of Plant Operations and Assets, hierarchical models were developed in PI AF following the structure defined in the SAP PM system, in addition to various calculations using PI Analytics and Notifications to users of critical signals using PI Notifications.
  • Resultados
  • Mine
    • Calculations were developed for the production of subway mines such as the amount of mineral extraction and waste from the shafts, counting the Skips x Hour, Shift and month, as well as monitoring signals from hoisting winches showing indicators of bearing temperature, lubrication motors, reset states, hourmeters, etc. To equipment that had been isolated without information records for many years.
    • In the visualization part, Dashboards were built in PI Vision showing in real time the location of the Skips, the amount of ore and waste produced, the energy and hourmeters of the equipment. Visualizing the processes in real time from any location through multiple devices.
    • PI Datalink operation reports were made for main ore extraction and skips x hour reports.
  • Plant
    • Mapped the signals from the crushing, grinding, flotation and tailings processes into the PI AF model and performed tonnage production calculations by shifts and daily totals.
    • Reporting was developed in PI Datalink as the Daily and Monthly Report, obtaining tonnage and grades from the PI System.
    • PI Vision displays were designed for the visualization of the crushing, grinding, flotation and Tailings circuits.
    • We made deployments for monitoring the bearing temperature, lubrication motors, status of each motor, hours of operation, and visualization of different Operational signals of the Assets.
    • The integration of the main ION energy meters to the PI System was carried out in order to proceed with the inclusion in the hierarchical model of PI AF.
    • The creation and development of the General Dashboard for Plant Operations was carried out, in order to visualize integrated information of the Mine production, laboratory grades, energy, and their respective trends.
  • Lima
    • The main operational signals were integrated into the infrastructure of the Corporate PI Server in Lima, which were used to perform the metallurgical balance. An HTML interface was implemented in the corporate PI Server to allow communication with the main metal price web pages.
    • The PI System also helped to correct automated signals that showed bad data and those that were not in use.
    • Finally, PI System training was conducted in each of the mining units, with the visualization tool courses in PI DataLink and PI Vision, so that the users themselves can further develop the PI Sytem.
    • In this way, Buenaventura Mining Company began to join the world of digitalization, monitoring its operations in real time for better decision making.
