• Description:
  Operators of longwall mining systems are exposed to sound levels of 93-105 dB(A) and receive noise exposures that place them at risk of noise-induced hearing loss. In previous field surveys, the sound radiated by the cutting drums was identified as a major hazard, especially considering the close proximity of the drums to the operators. In this context, the National Institute for Occupational Safety and Health (NIOSH) has used finite element (FE) and boundary element methods (BEM) to model and analyze the noise radiated by a cutting drum. Based on the analysis results, three conceptual noise controls for the cutting drum were developed and evaluated numerically. The simulation results indicate that promising noise reductions (3 dB(A) or more) can be achieved by all three developed noise control concepts, damping treatment, bit isolation, and structural modification. Due to the severe operating environment in longwall mines, structural modification is believed to be the most suitable noise control strategy. [Description provided by NIOSH]
