• Description:
  "This paper presents the preliminary safe distances for blasting wiring from typical electromagnetic sources. The distances are for underground coal mines and electromagnetic sources in the frequency range below 10 mhz. The distances are based on measurements performed at three locations in each of three coal mines. The measurement apparatus, measurement procedure, measurement results, and the rationale used in the calculation of the safe distances are all described. The safe distances presented are dependent on the measurement results and their interpretation. More measurements are clearly necessary to establish the validity of the suggested distances." - NIOSHTIC-2
