Surface Intake Fan Installation at Nickel Rim South

For the Nickel Rim South mine, BESTECH was instrumental in installing advanced surface intake fans to enhance underground air quality. Our role included advising on the electrical system design and leading the PLC and HMI programming. The installation of three high-capacity fans, complete with gas heaters and isolation dampers, significantly improved the airflow and temperature control in the mine’s underground areas. This project highlights BESTECH's ability to provide expert solutions in complex industrial environments.

Xstrata Nickel required the installation of surface intake fans at the Nickel Rim South mine to improve airflow and air quality in underground areas. The project demanded technical expertise in both the electrical system design and the programming of PLC and HMI components.

BESTECH played a crucial role in this project, advising on the electrical system design and leading the programming of PLC and HMI components. Our responsibilities extended to commissioning, post-system startup support, and the development of an “Operating, Maintenance and Surveillance Manual” for the system.

Key Features:

Installation of three 450 HP Howden Buffalo fans, each controlled by an Allen Bradley VFD.
Integration of gas-fired mine air heaters (37.0 MMBTHU) with each fan.
Implementation of electrically operated isolation dampers.
Programming of three Allen Bradley Control Logix PLCs and Rockwell RSView SE HMI stations.
Ensuring adequate fresh air delivery to underground areas, with a focus on optimal airflow and temperature control.

Completed between 2007 and 2008, the installation of these fans at Nickel Rim South ensured that a sufficient quantity and quality of fresh air were delivered to underground areas. The fans, operating in parallel, were key in maintaining ideal mine air flow, especially during the winter months. BESTECH’s contribution was pivotal in enhancing the mine’s ventilation system efficiency and safety.
