• Description:
  Magnetic Proximity Detection Systems (PDSs) are widely used in the mining industry for protecting mine workers from striking and pinning injuries when they work in close proximity to heavy machines such as Continuous Mining Machines (CMMs) and mobile haulage equipment. Researchers at the National Institute for Occupational Safety and Health (NIOSH) have conducted extensive measurement-based studies to investigate the performance of PDSs. To enable further investigation of scenarios for which physical measurements are impractical, a simulation-based approach is needed. In this paper, we present the development and validation of a simulation-based approach in which FEKO is used to model the magnetic field radiated from a ferrite rod antenna used in a commercial PDS. FEKO-based simulation results are compared to both analytical results and physical measurements and show good agreement. In addition, the major factors (including current, frequency, antenna length, antenna radius, number of turns and ferrite permeability) for controlling the magnetic field and thus the performance of a magnetic PDS are analyzed. This paper confirms that FEKO can accurately model the magnetic field radiated from a PDS antenna. The findings of the paper will help researchers and PDS manufacturers to better understand the magnetic field distribution of PDSs and design optimized PDSs that are more robust to underground mining environments.
