BESTECH provided structural and electrical engineering services for a new paste backfill feasibility study, building upon the 2019–2020 prefeasibility work.
This phase focused on advancing the process design and evaluating the required infrastructure. Unique challenges included a mountainous site with limited development space and considerable distance from existing mine infrastructure.
SCOPE
The feasibility study involved engineering a 1,550 m² pre-engineered building for paste backfill process equipment and a 20-tonne overhead crane. BESTECH designed a multi-level platform for elevated equipment, along with foundations for the building, platform, tanks, and other heavy equipment. Secondary containment systems were included to ensure environmental safety and regulatory compliance.
The engineering scope also encompassed exterior access platforms and stair towers for maintenance and operations. From an electrical standpoint, BESTECH prepared specifications and datasheets for major equipment, designed the electrical room layout, and completed cable routing, grounding layouts, block diagrams, and a detailed bill of materials.
OUTCOME
Engineering provided a technical roadmap for the proposed paste backfill plant, addressing site constraints. By integrating structural and electrical design principles, BESTECH offered a practical solution that supported the client’s goal of enhancing backfill capacity and mine productivity, positioning the project for detailed design and construction planning.
